  • cobalt processing Uses, Supply, & Facts Britannica

    For copper-cobalt ores, a sulfide concentrate is roasted under controlled conditions to transform most of the cobalt sulfide to a soluble sulfate while minimizing the change of copper and iron to their water-soluble states. The product is leached, the resulting solution is treated to remove copper and iron, and the cobalt is finally recovered by electrolysis. If the copper and cobalt ores are

    In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form

    Copper-cobalt ores are primarily found in Zambia and the DRC, where the cobalt is recovered from copper flotation concentrates, using a roast-leach-electrowin (RLE) process. The ore is roasted (for sulfides), followed by a sulfuric acid atmospheric leach, and direct electrowinning of copper. Impurity removal is a key step, as well as cobalt hydroxide precipitation. The final steps involve a re
