Which country is the primary source of rare earth elements?

• A. China
• B. Canada
• C. Brazil
• D. Japan

Answer: (A)

Rare earth elements are a group of minerals essential for many modern technologies, from magnets to catalysts. The country with the largest and most integrated mining and processing industry for these elements ends up supplying the majority of the world’s supply. This dominance comes from enormous reserves and a well-developed infrastructure, including the world’s largest rare earth ore body at Bayan Obo and mature refining capabilities. That combination of vast resources and established production makes this country the primary source of rare earth elements. Other nations like Canada, Brazil, and Japan do contribute some production, but their output and processing capacity are far smaller, so they don’t sit at the top of global supply.
