Copper Cobalt Ore Processing

Copper Cobalt Ore Processing

Cobalt extraction - Wikipedia

The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas. The remaining liquid is composed of a heavier copper smelt containing approximately 5% cobalt that is processed for its copper and a lighter slagthat is approximately 40% cobalt that is further refined by hydrometallurgical and electr

cobalt processing Uses, Supply, Facts Britannica

From copper and nickel processing. Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In ...
