For tin, the most lucrative conflict mineral in eastern Congo last year, 10 main smelting companies process over 80 percent of the world's tin, almost all of which are based in East Asia. [15] For tantalum, four companies make up the overwhelming majority of the chemical processing market, based in Germany, the U.S., China, and Kazakhstan.
The mining industry in the Democratic Republic of Congo has seen a significant expansion in copper and cobalt production in recent years. The greater proportion of this expansion has arisen through processing of oxide ores.
Due to its low concentration in ores, cobalt is usually considered to be a companion metal which is of limited economic interest. The bulk of global cobalt production emanates as a by-product of extraction of commodities such as copper (~55%), nickel (~35%), and arsenic (Azevedo et al., 2018, Smith, 2001).The only exceptions, which …
