Perfect separation of copper and cobalt by flotation is not possible: typical assays of the cobalt content of the copper-rich concentrate range between 0.5 and 0.25% (with copper assays between 28 and 32%), while the cobalt content of the cobalt-rich assays ranges between 2 and 3% (with copper assays between 6 and 13%).
Current Mining Methods for Cobalt Production: Cobalt is found primarily with mineral deposits of nickel and copper in the Earth. There are many different cobalt ores that are mined, involving many steps of separation and purification. The most well-known and mined ores are: nickel cobalt sulfide, copper cobalt sulfide, copper cobalt …
steadily. 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 …
