The UK critical minerals strategy sets legally-tracked targets to cut import dependence and build domestic supply resilience across mining, refining and recycling. Under the government’s Vision 2035 framework, the UK Critical Minerals Intelligence Centre (CMIC) tracks 34 minerals judged essential to the economy and vulnerable to supply disruption, spanning battery metals, defence-critical technology metals and industrial inputs.
UK Critical Minerals: The Vision 2035 Target Framework
Vision 2035 defines national resilience through three measurable benchmarks, each set against total annual industrial demand. At least 10% of UK critical mineral needs must come from primary domestic extraction, processing and refining, including a baseline of 50,000 tonnes of battery-grade lithium. A further 20% of demand must be met through recycling and recovery from end-of-life products. A 60% diversification cap prevents any single country from supplying more than 60% of an individual mineral to the UK, directly targeting China’s dominance in refined battery and magnet materials.
What Minerals Are on the UK’s Critical List?
CMIC’s list of 34 covers three broad categories: minerals essential to the green transition (lithium, cobalt, nickel, manganese, natural graphite, rare earth elements), high-tech and defence inputs (platinum group metals, gallium, germanium, indium, tungsten, tantalum, niobium), and industrial essentials (aluminium, silicon, magnesium, magnesite, antimony, tin, zinc, phosphorus). A parallel “Growth Minerals” list tracks materials such as copper and uranium that are not in immediate supply crisis but are considered vital to future industrial capacity.
UK Domestic Mining and Processing Hubs
The UK imports nearly all its raw critical minerals today, but exploration and midstream investment are concentrated in four regional clusters. Cornwall hosts tungsten and tin deposits alongside hard-rock and geothermal lithium extraction. County Durham and Teesside are developing as lithium conversion and urban-mining centres for processing electronic waste. Aberdeenshire is an active exploration target for nickel and cobalt, while Anglesey and Mid-Tyrone are being explored for copper, zinc, tellurium and antimony. London remains the financial centre of the sector, with the London Metal Exchange and London Stock Exchange functioning as the primary venues for mining project finance.
Key Companies Building UK Domestic Supply
Cornish Lithium is the flagship domestic extraction company, having produced the UK’s first lithium hydroxide refined from granite at its Trelavour site, alongside geothermal brine extraction. British Lithium operates a Cornwall pilot plant processing lithium from mica minerals. Northern Lithium is drilling high-grade lithium brines in the Weardale area of County Durham. On the midstream side, Tees Valley Lithium and Green Lithium are both developing independent lithium hydroxide refineries at Teesside, targeting battery-grade output for European EV manufacturers. Anglo American is building an automated polyhalite mine in the North York Moors, linked by a 37km tunnel to a Teesside processing plant. Johnson Matthey operates established UK refineries for platinum group metals and hydrogen technology components.

Government Funding and Industry Bodies
The UK has committed £50 million through the Critical Minerals Programme, split across three initiatives: a £20 million Magnet Hub scaling rare earth magnet recycling and manufacturing, a £25 million Critical Minerals Accelerator grant fund for midstream extraction and refining pilots, and a £5 million Demand Aggregation Platform pooling manufacturer demand to secure better international offtake terms. UK Export Finance separately issues loan guarantees to overseas mining projects that commit to long-term export supply back into British industry. Industry coordination runs through the Critical Minerals Association (CMA UK), which represents private mining, processing and recycling companies, and CMIC, run jointly by the British Geological Survey and the Department for Business and Trade.
UK Critical Minerals Supply Chain Risk
Despite the domestic build-out, the UK’s near-total reliance on imports for refined critical minerals leaves procurement and defence supply chains exposed to the same China-concentration risk driving policy elsewhere in Europe and North America. The 60% diversification cap is the UK’s direct policy response, but achieving it depends on the Teesside and Cornwall refining projects reaching commercial scale — most remain at pilot or demonstration stage. For UK-based technology metals processing already in commercial operation, see CMN’s profile of Sheffield-based Advanced Alloy Services, and for how UK producers rank against European peers, see CMN’s Top 10 Critical Minerals Companies in the UK.
UK Critical Minerals in the European Context
The UK’s targets sit alongside, but outside, the EU’s Critical Raw Materials Act framework — both pursue similar diversification logic on separate legal tracks post-Brexit. For the EU comparison, see CMN’s EU Critical Minerals Strategy coverage.

What are UK critical minerals?
UK critical minerals are the 34 minerals identified by the UK Critical Minerals Intelligence Centre as economically essential and vulnerable to supply disruption, spanning battery metals, defence technology inputs and industrial materials.
What is the UK’s Vision 2035 critical minerals target?
Vision 2035 targets 10% of demand from domestic production, 20% from recycling and recovery, and caps any single country’s share of supply at 60% for any individual mineral.
Where does the UK mine critical minerals domestically?
The main UK exploration and processing hubs are Cornwall (lithium, tungsten, tin), Teesside and County Durham (lithium refining, urban mining), Aberdeenshire (nickel, cobalt) and Anglesey/Mid-Tyrone (copper, zinc, tellurium, antimony).
Which companies lead UK critical minerals production?
Cornish Lithium, British Lithium and Northern Lithium lead domestic lithium extraction; Tees Valley Lithium and Green Lithium are building midstream refining capacity; Anglo American and Johnson Matthey operate established processing operations.
How much has the UK government committed to critical minerals funding?
£50 million through the Critical Minerals Programme, split between a £20 million magnet recycling hub, a £25 million midstream refining accelerator, and a £5 million demand aggregation platform.
Does the UK rely on imports for critical minerals?
Yes, the UK currently imports nearly all its raw critical minerals, which is the core problem Vision 2035’s targets are designed to address over the next decade.
