Critical minerals companies China has built since the 2010s now span far beyond rare earths — controlling the bulk of global lithium chemical conversion, the world’s largest cobalt and copper-cobalt operations, and dominant positions in tin, tungsten and battery recycling. For procurement teams and investors mapping supply chain exposure, this concentration outside the rare earth sector is often underestimated next to the headline REE story.
How We Ranked the Top 10 Critical Minerals Companies China
This list ranks critical minerals companies China by global market share in their core mineral, scale of overseas asset ownership, value-chain integration, and strategic significance to Western supply chain planning. Companies whose primary business is rare earth mining or separation are excluded here — see Rare Earth Mining’s ranking of Chinese rare earth producers for that segment.
1. CMOC Group Limited — Democratic Republic of Congo / China (603993.SH, 3993.HK)
CMOC is the world’s largest cobalt producer and a top-five copper producer, built on its Tenke Fungurume and Kisanfu operations in the DRC. The company also holds significant molybdenum and tungsten assets domestically. CMOC’s DRC output gives China effective control over the largest single source of battery-grade cobalt feedstock globally — a position with no near-term Western equivalent. See CMN’s full CMOC company profile for production detail and DoD-adjacent supply chain context.
2. Ganfeng Lithium Co., Ltd. — Jiangxi, China (002460.SZ, 1772.HK)
Ganfeng is one of the world’s largest lithium chemical producers, with equity stakes and offtake agreements spanning Australia’s Mt Marion, Argentina’s Cauchari-Olaroz, and Mali’s Goulamina. Its integration from brine and hard-rock feedstock through to lithium hydroxide and battery-grade carbonate makes it a structural counterparty for Western and Asian battery makers alike, even where the raw lithium itself is mined outside China.
3. Tianqi Lithium Corporation — Sichuan, China (002466.SZ, 9696.HK)
Tianqi holds a major stake in Australia’s Greenbushes, the world’s largest hard-rock spodumene deposit, alongside a 24% stake in Chile’s SQM. The combination gives Tianqi exposure to both of the world’s premier lithium resource bases. Full detail on its Greenbushes position is covered in CMN’s Tianqi Lithium profile.
4. Zijin Mining Group Co., Ltd. — Fujian, China (601899.SH, 2899.HK)
Zijin ranks among the world’s largest diversified miners by reserves, with copper, gold and zinc assets spanning the DRC, Serbia and South America — including a stake in the Kamoa-Kakula copper complex. Its rapid overseas acquisition strategy since 2015 has made it one of the most geographically diversified Chinese mining groups, reducing single-jurisdiction risk relative to domestic-only peers.
5. Huayou Cobalt Co., Ltd. — Zhejiang, China (603799.SH)
Huayou is a leading integrated cobalt and nickel precursor producer, supplying cathode precursor materials directly to battery cell manufacturers. The company has expanded into Indonesian nickel processing in joint ventures, positioning it across both the DRC cobalt and Indonesian nickel battery-metals corridors simultaneously — two of the most geopolitically sensitive supply chains in the energy transition.
6. Sinomine Resource Group Co., Ltd. — Beijing, China (002738.SZ)
Sinomine holds a global monopoly-adjacent position in cesium and rubidium via Canada’s Tanco Mine, alongside an expanding African lithium portfolio including Zimbabwe’s Bikita mine. Its niche-metal dominance, though small in absolute tonnage next to lithium or cobalt majors, makes it a name-brand example of Chinese strategy in thinly-traded specialty minerals with concentrated single-source supply.
7. Xiamen Tungsten Co., Ltd. — Fujian, China (600549.SH)
Xiamen Tungsten is the most diversified company on this list outside its rare earth exposure, combining tungsten mining and processing with a separately listed battery materials subsidiary on the STAR Market. Its tungsten business supplies cemented carbide for defence and industrial tooling applications, a separate critical-minerals risk vector from its REE-adjacent activities, which are covered in REM’s rare earth ranking.
8. GEM Co., Ltd. — Shenzhen, China (002340.SZ)
GEM is one of China’s largest battery recycling and precursor materials companies, recovering cobalt, nickel and lithium from end-of-life batteries and electronic waste at industrial scale. As Western recycling capacity remains nascent, GEM’s recovery volumes represent a meaningful secondary supply source that reduces China’s net reliance on virgin ore imports for battery metals.
9. Aluminum Corporation of China Limited (Chinalco) — Beijing, China (601600.SH, 2600.HK)
Chinalco is China’s dominant state-owned aluminium and bauxite producer, with growing copper and rare and precious metals trading divisions. Its scale in bauxite and alumina — both on multiple national critical minerals lists — and its central role in China’s strategic metals reserve system give it broader policy significance than its core aluminium business alone would suggest.
10. Yunnan Tin Group Co., Ltd. — Yunnan, China (000960.SZ)
Yunnan Tin is the world’s largest tin producer and refiner, controlling roughly half of China’s domestic tin smelting capacity. Tin’s role in solder for semiconductor and electronics manufacturing keeps it on Western critical minerals lists despite its low public profile relative to lithium or cobalt, and Yunnan Tin’s market share gives it outsized pricing influence globally.

The Outlook for Critical Minerals Companies China in 2026
The next twelve months will test how far these critical minerals companies China relies on can keep diversifying overseas asset bases without triggering further Western screening of Chinese-linked offtake and equity positions — a dynamic already playing out around CMOC’s DRC cobalt and Ganfeng’s Argentine lithium stakes. Battery recycling players like GEM are likely to gain relative strategic weight as virgin ore access tightens in some jurisdictions, while tin and tungsten remain underweighted in Western critical minerals strategy relative to their semiconductor and defence exposure.

Who is the #1 critical minerals company in China and why?
CMOC Group ranks first among critical minerals companies China hosts, based on its position as the world’s largest cobalt producer and a top-five copper producer through its DRC operations at Tenke Fungurume and Kisanfu.
What criteria determines this ranking?
Companies are ranked by global market share in their core mineral, scale of overseas asset ownership, value-chain integration, and strategic significance to Western supply chain planning, excluding companies whose primary business is rare earth mining or separation.
Why are Chinese rare earth giants like China Northern Rare Earth not on this list?
Rare earth-dominant companies fall under sister site Rare Earth Mining’s editorial coverage rather than CMN’s broader critical minerals remit, and are linked to directly rather than duplicated here.
Which company on this list has the most diversified overseas mining footprint?
Zijin Mining holds the broadest international footprint, with copper, gold and zinc assets across the DRC, Serbia and South America, including a stake in the Kamoa-Kakula copper complex.
What could change this ranking in the next year?
Further Western screening of Chinese-linked equity and offtake positions in DRC cobalt and South American lithium assets, alongside the growth of battery recycling capacity, are the two clearest forces that could reorder this list.
