How China Dominates the World’s Critical Minerals Production

Kyle McCollum

Critical minerals are mined all over the world but the majority of the supply ends up passing through China. For a broad range of key metals and minerals, China is either the largest miner, the dominant refiner, or both. This is true for rare earths, lithium, cobalt, graphite, nickel, and many other metals and minerals that are essential to defense, energy and high-tech applications. It is less about where ores are dug out of the ground and more about where they are turned into usable components. In other words, Chinese processing plants are essentially the gatekeepers of global supply.

Australia and South America host much of the world’s lithium, while Congo supplies the lion’s share of cobalt and copper. But the rocks themselves can’t become a battery or magnet without intensive downstream processing and refining. China built those downstream industries at scale over decades through state support and investment. The result is clear — China has effectively monopolized refining for most critical minerals while the rest of the world depends on it for much-needed supply. China is listed as the dominant refiner for 19 of 20 minerals analyzed by the IEA in their Global Critical Minerals Outlook for 2025, making up roughly 70% of the global processing capacity overall.
