copper and cobalt production process Prominer Mining

Cobalt is produced mostly as a by-product of other major metal extraction processes – mainly copper and nickel – and in recent decades the nickel industry has been the major source of cobalt. Now however the Democratic Republic of Congo DRC copper-cobalt production is coming to the fore once again after a 20-year period of decline.
