The UK has relatively diverse and large deposits of minerals that have been mined historically.

Key sectors include:

  • Construction minerals – aggregates, brick clay and cement raw materials;
  • Industrial minerals – kaolin (china clay) and ball clay, silica sand, gypsum, potash, polyhalite, salt, industrial carbonates, fluorspar and barytes; and
  • Metal minerals – tungsten, gold.
  • Energy minerals – coal;

The largest bulk market for non-energy minerals is construction. Industrial minerals extracted and used in the UK range from those used primarily domestically (for example, silica sand and limestone for glassmaking, iron and steel manufacture) and minerals such as kaolin, ball clay and potash, which have significant international markets. Mineral production supports a wide variety of upstream, midstream and downstream industries. 

Cornish Lithium recently reported it has found “globally significant” lithium grades in geothermal waters and is preparing for work on its pilot plant. Cornwall Resources are also moving forward with the development of their Redmoor project, of a significant tin, tungsten and copper deposit and a mining scoping study has recently been completed. The significant resource of gold at Curraghinalt in Northern Ireland (Dalradian) and Cononish in Scotland (Scotgold), where a recent announcement has been made to accelerate plans to double production, are other exciting examples that illustrate the continuing importance of the UK as a mineral producer.The South Crofty project is working towards the reopening of the South Crofty tin mine in Cornwall.

Non-energy UK mining and quarrying has been broadly flat in recent years while coal production volumes have consistently fallen for the past three decades. A planned new coal mine at the Woodhouse Colliery, near Whitehaven, was originally approved to provide metallurgical or coking coal for use in steel production. This decision is now subject to a public inquiry.

Production and Trade

Although the UK has significant domestic supply of some minerals, it is a net importer of many minerals and mineral-based products, particularly metals, and in the long term has experienced a balance of trade deficit.

UK mineral exports and imports have both increased in recent years. However, imports and exports of the largest minerals flow, aggregates, are relatively low, accounting for less than 5% of the market [1]. 

The Office for National Statistics (ONS) publishes data on the volume of production and trade of metal ores and non-metallic minerals in its material flows account for the UK while they also report on the value of imports and exports. These data have yet to be verified so they are not included here to avoid giving a misleading impression of the scale of the sector.

The British Geological Survey (BGS) produce a periodic United Kingdom Minerals handbook which includes statistical data on the production of UK mineral resources including construction, industrial and metal minerals. 

The Mineral Products Association (MPA) also produces a periodic Profile of the UK Mineral Products Industry, which sheds light on the breadth of the minerals and manufactured mineral products industry, from the diversity of the products and their uses, the scale of their markets, to their environmental and sustainability attributes. 

Production data is also available from the annual Digest of UK Energy Statistics (DUKES) and supply and demand data via the monthly Energy Trends statistics.

Legal framework

Extraction of minerals is subject to the UK’s mineral planning process. The aim of mineral planning is to facilitate the sustainable supply and use of minerals. Mineral working is not a permanent use of land, and extraction sites are usually restored for beneficial after-use.

Mineral planning policy is devolved and set out in the National Planning Policy Framework (England), Planning Policy Wales and National Planning Framework for Scotland 3. In Northern Ireland, policy and guidance are provided through documents such as the Strategic Planning Policy Statement for Northern Ireland, which partly supersedes the Planning Strategy for Rural Northern Ireland. In Northern Ireland since 1 April 2015 responsibility for planning is shared between the Department of the Environment (from 8th May 2016 in respect of planning, the Department of Infrastructure and the eleven local councils).

Exploration for and extraction of metalliferous and industrial minerals are licensed by the Department for the Economy in Northern Ireland under the Mineral Development (Northern Ireland) Act 1969. The UK framework is supported by technical documents providing guidance on particular issues of mineral planning. The focus of the mineral planning process is on whether the development itself is an acceptable use of the land [2]. 

Mineral planning and decisions on planning applications are a responsibility of a local authority body referred to as mineral planning authorities (MPAs). In Wales, Scotland and some parts of England MPAs are Unitary Authorities. In Wales, Local Planning Authorities including Local Authorities and National Parks Authorities are responsible for minerals planning. In most of England MPAs are the County Councils or National Parks. In Northern Ireland, the Minerals Unit, part of the Planning Service of the Department of the Environment, was responsible for minerals planning until 1 April 2015 [3]. 

MPAs have four areas of planning responsibility:

  • Planning to guide future developments;
  • Safeguarding mineral resources;
  • Managing developments by deciding on planning applications; and
  • Monitoring and enforcement of existing planning permissions.

Some minerals permissions last for many years, and there may be a need for periodic reviews of the planning conditions attached to that permission. MPAs control mineral developments under the orders established under the Town and Country Planning Act 1990 (Section 97, Part II of Schedule 5, and Schedule 9) [4]. 

Minerals extraction may only take place if the operator has the agreement of the landowner and has obtained both a planning permission from the mineral planning authority and any other permits and approvals. The latter may include:

  • Permits relating to surface water, groundwater and mining waste, issued by the Environment Agency (under UK legislation related to the EU Water Framework Directive and Mining Waste Directive);
  • Where appropriate, European Protected Species Licences, issued by Natural England;
  • Where appropriate heritage asset consents issued by Historic England;
  • Licences for exploration and extraction of coal, or agreements to enter into or pass through a coal seam to extract any other mineral, need to be granted by the Coal Authority; and
  • Licences for exploration and extraction of minerals managed by The Crown Estate (TCE) need to be obtained from the latter [5]. 

Additional consents, such as relating to diverting and reinstating rights of way or temporary road orders, may need to be obtained. Additional rights of way and land use may need to be secured from landowners. Active mining and quarrying operations are also regulated by the Health and Safety Executive (in Great Britain). The corresponding Northern Ireland regulatory authority is the Health and Safety Executive for Northern Ireland (HSENI)

Marine plans are being developed by each of the UK marine planning authorities in accordance with the requirements of the Marine and Coastal Access Act 2009 and the UK Marine Policy Statement. Each marine plan will set out policy to support public authorities determining licensing applications including those for marine minerals and oil and gas extraction [6]. 

A marine plan:

  • Sets out priorities and directions for future development within the plan area;
  • Informs sustainable use of marine resources; and
  • Helps marine users understand the best locations for their activities, including where new developments may be appropriate.

Relevant public authorities must take their decisions in accordance with the relevant marine planning documents, i.e. the UK Marine Policy Statement and any marine plan prepared and adopted by the marine planning authority.

Information about mineral planning and environmental permitting within the UK’s devolved administrations is available as follows:

Mineral ownership and licensing

With the exception of oil, gas, coal, gold and silver, mineral rights in Great Britain [7] vest in landowners rather than the state. It follows that there is no single, national licensing system for the exploration and extraction of such privately owned minerals.  While planning permissions and environmental permits are generally required for such purposes, these are not licences.

Where mineral rights belong to a private landowner, permission for exploration must be received from the landowner. As TCE and (in GB) the Forestry Commission manage land on behalf of The Crown, they also issue exploration and extraction licences for mineral deposits under their management and grant access right permits (wayleaves). In some cases, mineral rights can be managed by a private agent on behalf of a public body (TCE and Forestry Commission Scotland).

The MSG does not believe there are any non-trivial deviations in the award or transfer of licences for 2020 or previous years covering marine aggregates, marine licences, terrestrial mining licences, terrestrial mining licences, Northern Ireland licences and any other licences.

Northern Ireland

With certain exceptions, mineral rights in Northern Ireland [8] are vested in the Department for the Economy (DfE). The DfE publishes a description of the process for the award of Mineral Prospecting Licences (MPLs) and how to apply for licences to explore for and extract minerals and petroleum.  DfE also consults publicly on applications, which are accepted on a “first come, first served” basis, although there is provision for a competitive process where there is more than one interest in an area. Information on mineral prospecting licences and applications and mining licences is currently available on the DFE website.

The Crown Estate and Crown Estate Scotland: marine licences

The Crown Estate manages the seabed to the 12-nautical mile territorial limit and other rights including non-energy mineral rights out to 200 nautical miles in all parts of the UK excluding Scottish territorials waters and the Scottish offshore zone, where Crown Estate Scotland manages these rights.

TCE typically awards, through a market-based tendering process, commercial agreements to companies to explore for or extract marine aggregate minerals, and it collects royalties for minerals extracted. All licensed application and exploration/option marine aggregate area details are published online and are available at no charge. TCE does not disclose contracts and agreements relating to minerals where they contain commercially confidential information.

Following the successful completion of the 2018 Marine Aggregates tender, and recent engagement with the sector, TCE intend to hold their next tender round during 2021/22. This tendering process will offer applicants the opportunity to seek rights for the exploration of aggregates (sand and gravel) lying on or under the seabed, in offshore areas of English and Welsh waters.

Pre-qualification will commence in the spring of 2021, with the Invitation to Tender stage (ITT) beginning in the summer. Following tender evaluation and assessment, and subject to the requirements of a plan-level Habitats Regulations Assessment, rights could be awarded at the end of the summer of 2022. Successful applicants would then be required to obtain all relevant statutory consents prior to the commencement of activities. Once the Exploration and Option Agreement is completed, information will be added to the TCE Open Data Portal, including the name of the applicant.

There are no currently commercial marine aggregate extraction licenses in Scotland, future proposals would lead to an equivalent process with the relevant seabed manager.

Such rights and options can only be exercised once the necessary regulatory consent (marine licence) is obtained under the Marine and Coastal Access Act 2009 or Marine (Scotland) Act 2010 from the national regulator – the Marine Management Organisation (MMO) in England, Natural Resources Wales (NRW), Marine Scotland or in Northern Ireland the Department of Agriculture, Environment and Rural Affairs (DAERA) – according to location [9].  All regulators are required to keep a public register of marine licences they have issued [10]. Applications for marine licences must be publicised to allow anyone who is interested a chance to object [11]. 

Revenue streams for marine aggregates comprise:

  • Marine licence payments of fees and relevant charges to the relevant regulator; and
  • Rent and production royalty payments to TCE [12]. 

The Marine Aggregates Capability and Portfolio report published by TCE provides a summary of the current aggregate extraction activity offshore, as well as remaining reserves on the seabed around England, Wales and Northern Ireland.

TCE also provides access to survey data and reports collected by offshore renewable and marine aggregates customers via their Marine Data Exchange and access to all data that they publish via their Open Data Portal.

The Crown Estate and Crown Estate Scotland: terrestrial minerals

TCE also grants mineral leases across England and Wales (except in Scotland) for land-based mineral extraction operations, including sand, gravel, hard rock, dimension stone and slate. It charges royalties for minerals extracted. Lease conditions and royalty payment provisions are negotiated on an open market and case-by-case basis. Crown Estate Scotland undertakes the same process for minerals on Scottish Crown Estate assets.

TCE also manages the right to gold and silver (“Mines Royal”) [13], in England and Wales, but there is no significant gold or silver production in these areas. 

In Northern Ireland under the Mineral Development (Northern Ireland) Act 1969 with certain exceptions (exceptions include gold and silver) all mineral rights are vested in the Department for the Economy (DfE). Since 1970 the mineral rights specified in the 1969 Act are held in public ownership.

In Scotland, Crown Estate Scotland manages the rights to Mines Royal across most of Scotland. Planning permission was granted in Autumn 2018 for a gold mine at Cononish, Tyndrum. Crown Estate Scotland has granted lease rights to the operator for the extraction of gold and silver.

Local Planning Authorities (planning obligations payments)

Planning obligations are agreements made between a planning applicant (including the freehold owner of land where the operator only has a minerals lease) and a Local Planning Authority (LPA) under section 106 of the Town and Country Planning Act 1990 in England and Wales, section 75 of the Town and Country Planning (Scotland) Act 1997 (as amended by the Planning etc. (Scotland) Act 2006) in Scotland and Article 40 of the Planning (Northern Ireland) Order 1991. Planning obligation payments are site-specific and negotiated case by case. They may comprise:

  • Monetary payments to LPAs; or
  • “In-kind” infrastructure provisions: mainly off-site provisions, (on-site provisions within the boundary of a planning permission are theoretically possible but more likely to be included in planning conditions rather than under planning obligations).

The difference between off- and on-site “in-kind” infrastructure provisions can be understood as between provisions that benefit the local community and those used by the extractive company itself. Only monetary payments and off-site provisions are in scope for the UK EITI.

Planning obligations can be short term, such as obligations to carry out works before the extraction can take place, or long term, such as obligations to restore or provide after-care of extraction sites.

Obligations are recorded in online planning registries kept by LPAs, but payments owed or made are not always recorded, and no central registry of such planning obligations or relevant payments exists.

Fiscal regime

Mining and quarrying companies pay corporation tax (CT) on their profits at the standard rate, unlike profits from oil and gas extraction, which are subject to Ring Fence CT regime. Profits from upstream and downstream activities are not separated, and such companies pay a single amount of CT on the profits arising from all their activities. It is therefore not possible to say how much of the taxes paid by the companies whose tax payments are reported here related to their extractive activities nor what the total of such taxes was (and therefore what proportion of the total is covered by this report).

Companies based in the UK have to pay CT on all their taxable profits, wherever in the world those profits originate, although double taxation relief is available where appropriate to avoid the same profits being taxed twice. Companies not based in the UK, but with branches operating in the UK, have to pay CT on taxable profits arising from their UK activities. CT payments by mining and quarrying companies are included in the scope of the UK EITI. The figures reported are for total CT and include tax on both upstream and downstream activities. Corporation tax is paid by a small number of larger companies whose activities are primarily downstream.

Capital allowances are a feature of business taxation in the UK and apply to the mainstream CT regime (as well as to income tax). For CT purposes, the general rule is that capital expenditure is not allowed as a deduction for tax purposes. This means that profits chargeable to CT cannot be reduced by depreciation or similar expenses. The capital allowance regime exists to provide some relief for capital expenditure incurred.  The main allowance which is commonly relevant for companies carrying on mining and quarrying activities is Mineral Extraction Allowance (MEA).   

Research and Development Expenditure Credit (RDEC) is a tax credit available to companies operating in all sectors. It is generated by spend on research and development, and is claimed as a tax credit. There are a number of ways in which a company can receive payment of their RDEC claim, including offsetting against another of its tax liabilities and receiving a cash repayment. More information on RDEC can be found in HMRC guidance and statistics on RDEC can be found here. For EITI reporting purposes, tax payments/repayments are reported exclusive of any adjustment for RDEC.

There are several other payment streams, such as the Aggregates Levy, which involve payments from extractive companies to the Exchequer. These are outside the scope of EITI as they are indirect taxes not direct taxes. They are documented by the ONS in its annual publications on environmental accounts and environmental taxes [14].


Ahead of collection and publication of information on extractive-related payments to the UK government in 2018, the UK EITI Multi-Stakeholder Group decided to exclude such payments to the Coal Authority. These payments are no longer material relative to overall government revenues and the MSG believes that their exclusion will not affect the comprehensiveness of UK EITI reporting. The continuing economic contribution of the coal sector is, though, still included in the background information set out below.

The Coal Authority is a regulatory executive non-departmental public body, established in 1994 when the industry was privatised.  It is sponsored by BEIS. The Authority owns, on behalf of the State, the majority of unworked coal and abandoned underground coal mine workings in GB and regulates and grants licences for working of coal and underground coal gasification (UCG), together with agreements to enter its coal estate for other processes such as coal bed methane extraction, abandoned mine methane extraction, mine water heat recovery and deep energy exploitation (e.g. geothermal, shale gas).

The Coal Authority holds an offline public registry of licences and does not publish licences online. Information about coal licences can be requested by post and email [15]. The Authority provides online coal mining data including on licence areas and known areas of activity. 

Coal Authority revenue streams include: 

  • Fees for statutory licences, either operating or conditional (where the licensee is yet to secure planning permission) for surface and underground coal mining operations and UCG;
  • Fees for licences for coal exploration;
  • Production-related rents under coal leases which transfer the property interest in the coal to the licensee when holding an operating licence;
  • Fees and royalties for digging and carrying away coal during non-coal-related development (Incidental Coal Agreement);
  • Fees for agreements to access or pass through the Authority’s coal estate for processes such as coal bed methane and abandoned mine methane extraction, mine water heat recovery and deep energy exploitation (e.g. geothermal, shale gas); and
  • Payments for coal rights under options for lease (granted with conditional licences) and rights for pillars of support in coal.

Further information on licensing activity can be obtained from the Coal Authority.

The majority of coal output comes from surface mining (opencast) sites in Scotland, North East England and South Wales. UK coal production peaked in 1913 and has been contracting, with fluctuations, since the mid-twentieth century, with the sharpest decline in the 1990s. Electricity-generating power stations currently account for most of the UK’s coal consumption.

The Coal Authority acts as an agent on behalf of the consolidated fund. Amounts collected and payable to the consolidated fund are reduced to cover the Coal Authority’s cost of collection. This income adjustment is included within Licensing and permissions indemnities income given above.

Production related rent is earned on each tonne of coal extracted from existing operating coal mining sites. Incidental coal is royalty income from other sites where coal production is incidental to the main purpose of the activity being carried out.

Options for lease for future coal mining sites are granted in the form of a conditional licence and option for lease for the coal and income is recognised on the granting of the option. The site cannot become operational until certain conditions (for example, planning consent) have been met and payments are made annually based on the area of the option.

Property sale proceeds are recognised within the consolidated fund income where the initial purchase was made from grant in aid in previous periods. Income is recognised following the exchange of contracts and on completion of the sale of property.

Cost of collection relates to the element of income retained to finance licensing activities and the cost of any unrecoverable amounts owed.

Balances held at end of year represent amounts still to be remitted to the consolidated fund.

Construction Minerals

Construction minerals include the extraction of igneous rock (including granite), limestone, dolomite and chalk for construction use, sandstone, sand & gravel, slate, gypsum, clay & shale and fireclay. Brick clay is an essential raw material for the manufacture of bricks; limestone and chalk are the primary materials for the production of cement.

Primary aggregates are the largest flow of construction minerals in tonnage terms. In the UK, the total supply of aggregates includes crushed rock and sand & gravel (from land-won and marine-dredged), with significant contributions from recycled and secondary materials. According to the Mineral Products Association, in 2019 the UK industry produced 199 million tonnes of primary aggregates. Regionally most (67% of) UK primary aggregates production in 2019 took place in England, 15% in Scotland, 12% in Northern Ireland and 7% in Wales [16]. This includes both land-won and marine dredged aggregates.

Marine dredged sand & gravel provides a strategic role in supplying large scale coast defence and beach replenishment projects – over 30 million tonnes being used for this purpose since the mid 1990’s. With the growing threats posed by sea level rise and increased storminess, the use of marine sand and gravel to protect vulnerable communities and infrastructure around our coast will become increasingly important. In 2019, 1079 km2 of seabed was licensed for marine aggregate extraction in British waters, of which 105 km2 was dredged. This represents just 0.12% and 0.01% of the total UK continental shelf area (867,000km2) respectively[17].

The UK is a net exporter of aggregates, although both imports and exports represent less than 5% of UK markets. Because transport costs are a very significant factor for aggregates, most markets are local or regional, with relatively little international trade. Historically, the UK has been self-sufficient in the supply of primary aggregates due to significant geological resources and adequate reserves with planning permissions. Exports of UK aggregates were valued at £59 million in 2021, compared with imports worth £52 million [18].

Further detailed information on the extraction and manufacturing of non-energy and non-metals minerals and mineral products is available on table 3. A total of 400 million tonnes of essential aggregates, industrial minerals and other manufactured mineral products were produced in Great Britain in 2018.

Other data can also be found from the British Geological Survey (BGS) Minerals Yearbook.


Table 3 Minerals and Mineral Product Sales in Great Britain, 2018 (million tonnes)

Source: Profile of the UK Mineral Products Industry 2020 (January 2021)

Trends in demand and supply for construction minerals are closely linked to the overall UK economic and construction activity.

Following a 9.3% contraction in UK Gross Domestic Product (GDP) as a result of Covid-19, the UK economy posted a record-breaking 7.4% annual growth in 2021 compared with 2020. Since then however, a combination of supply chain bottlenecks, labour and raw material shortages, and soaring energy prices have challenged many industries and slowed momentum, holding back growth and pushing inflation.

The construction supply chain has been at the forefront of bottlenecks and rising costs. Rising prices for raw materials, energy and labour started to impact projects on the ground in the second half of 2021, although total construction output nonetheless leapt back above pre-Covid-19 levels at the end of 2021. Overall, total construction output rose by 12.9% in 2021 compared to 2020, driven by work in infrastructure, private housing repair & maintenance, and non-housing repair & maintenance.

As a result of this rapid rebound in activity, construction demand for aggregates and other mineral products also recorded double-digit growth during 2021. The tonnages of primary aggregates sales rose by 15.7% on an annual basis in 2021, 14.1% for ready-mixed concrete, 12.5% for asphalt and 24.4% for mortar. Within aggregates, crushed rock demand was supported, in particular by the acceleration in infrastructure work, including roads and major infrastructure projects such as High Speed 2, a high-speed railway line that is under construction between London and Wigan, via Birmingham and Manchester. This boosted the demand for fill materials and asphalt manufacture. By contrast, the recovery in ready-mixed concrete demand is being held back by a weaker recovery in new commercial tower projects and is dragging on the recovery in demand for sand & gravel, two-third of which is used in the manufacture of concrete.

Momentum in construction activity and aggregates demand continued in the first half of 2022, with infrastructure work set to remain a key driver of activity over the next few years, underpinned by work progressing under the 5-year spending plans within the regulated sectors (in roads, rail, energy and water), and momentum building up on major projects, including Hinkley Point C, the Thames Tideway tunnel and High Speed 2. However, the resilience of the construction supply chain will be severely tested by the unfolding ‘cost of living’ and ‘cost of doing business‘ twin-crises, as a result of a combination of global supply-chain bottlenecks, elevated prices for raw materials, energy and labour costs, and heightened economic and geopolitical uncertainty.



Industrial Minerals

Please note that not all final production figures for 2020 for industrial minerals are available yet.

Industrial minerals include a number of raw materials used in specialised processes, with notable production in the UK of the following [19]. 

Kaolin - Kaolin, also known as china clay, is a commercial clay with specialist applications in paper production, ceramics, cosmetics and other industries. UK deposits of kaolin are concentrated in Cornwall and Devon and are world-class in terms of size and quality [20]. 

Production peaked in 1988 at 2.8 million tonnes but since then has declined to an estimated 635 thousand tonnes in 2020, 90% of which was exported, mostly to Europe.

Ball clay - Ball clay, another major industrial mineral, is produced in Devon and Dorset mainly for the manufacture of white ware ceramics. Production levels peaked between 2005 and 2008 at more than 1 million tonnes. In 2020, production was estimated at 696,000 tonnes and exports reached 527,551 tonnes.

Production of potash (a processed product also known as muriate of potash, or MOP) has now ceased and has been replaced by polyhalite, an unprocessed mixture of potassium minerals. Production of polyhalite was 709,000 tonnes in 2020.

Yorkshire has one of the largest proven world deposits of potassium-rich minerals. There is one potash mine in the UK, at Boulby, Yorkshire, which currently produces approximately 1 million tonnes per year of polyhalite and directly employs 1,000 people, half of whom work underground [21],

In June 2015 a planning application was approved for another mine in the North York Moors (NYM) National Park.  

The Woodsmith Mine, an Anglo-American project, currently in development is the UK’s biggest underground mining project for many years. Based in North Yorkshire it will mine, process and supply polyhalite an organic crop fertiliser.

Salt - England accounts for 95% of UK salt production, 80% of which takes place in Cheshire; the Boulby potash mine in Yorkshire is another large centre. About 70% of salt is extracted through solution mining, the rest mined as rock. County Antrim is the main area of salt production in Northern Ireland. Rock salt is primarily used for de-icing roads and in agriculture. Brine salt is chiefly used in chemical industrial processes that require chlorine. An estimated 2.312 million tonnes of salt were produced in the UK in 2020 with exports estimated at 374,671 tonnes. The Winsford Salt mine, an underground mine in Cheshire, produces rock salt for road treatment in winter.

Silica sands contain a high proportion of silica and their properties make them essential for glass making and a wide range of other industrial and horticultural applications. UK production has declined from approaching 7 million tonnes in 1974 to an estimated 5.3 million tonnes in 2020. Exports were estimated to be 189,890 tonnes in 2020.

Gypsum - Natural gypsum is used in plaster, plasterboard and cement making and has historically been mainly extracted by mining in the UK. The amount extracted in the UK has declined appreciably because of the use of desulphogypsum derived from flue gas desulphurisation at coal-fired power stations. In 2020 the UK produced an estimated 1.3 million tonnes, with exports of 21,126 tonnes.

British Gypsum operates 5 sites throughout the UK extracting gypsum for the production of plaster and plasterboards.

Industrial and agricultural carbonates are important in iron and steel making, sugar refining and glass making, as fillers in various products, to reduce soil acidity in agriculture, and for flue gas desulphurisation in coal fired power generation. Total industrial carbonates production peaked at around 11.5 million tonnes in the late 1990s but was around 9 million tonnes in 2014.

Fluorspar is the most important and only UK source of the element fluorine, most of which is used in the manufacture of hydrofluoric acid. It is extracted from the Southern Pennine ore field in the Peak District National Park. In 2020, an estimated 15,000 tonnes were extracted, with exports estimated to be 15,053 tonnes.

British Fluorspar operates one underground mine in the Peak District and undertaking studies as to reopen an older operation. Mines and processes acid grade fluorspar a key raw material for the production of hydrofluoric acid, fluorocarbons, fluoropolymers and aluminium fluoride. These chemicals are used in a variety of industries such as the automotive, electronic, construction and chemical industries as well as in the production of aluminium and steel.

Barytes is principally used as a weighting agent in drilling fluids used in hydrocarbon exploration, to which its fortunes have been linked. The major source comes from the Foss mine near Aberfeldy in Scotland. Production in 2020 was estimated to be 50,000 tonnes. Exports for 2020 amounted to 13,221 tonnes.

M-I SWACO operates one underground mine (Foss Mine) in Scotland and developing a second mine (Dunanlich) producing barytes mainly used in the oil and gas industry in drilling fluids.


Metal Minerals

Tungsten (wolfram) is an essential element in a range of industrial processes, valued for its high melting point, density and extreme strength. England hosts the world’s fourth largest known tungsten deposit – the Drakelands Mine near Plympton, Devon.

This has been estimated to contain 318,800 tonnes of tungsten metal, or about 10% of the world’s known reserves, as well as an estimated 43,700 tonnes of tin. Production at Drakelands, historically known as Hemerdon mine, began in 2015 after a 70-year break, operated by Australian company Wolf Minerals, but stopped in 2018 following the operating company going into administration [22]. 

In 2018 production of tungsten was estimated to be 1,240 tonnes in the UK, with exports estimated to be in the region of 1,507 tonnes in 2020 (including scrap, unwrought, wrought, carbide and ferro-tungsten).

The above data are sourced from the BGS “World Mineral Production” and United Kingdom Minerals Yearbook 2021 publications and cover extraction from 2016–2020.
