Cobalt Wikipedia

Changes that Congo made to mining laws in 2002 attracted new investments in Congolese copper and cobalt projects. Glencore's Mutanda mine shipped 24,500 tons of cobalt last year, 40% of Congo DRC's output and nearly a quarter of global production. Glencore's Katanga Mining project is resuming as well and should produce 300,000 tons of copper
