COPPER LEACH FROM BLACK COPPER MINERALS

The minerals MS and LB present similar behaviour in leaching under all studied conditions, and both samples can be classified as copper wad. The standard leaching condition produces a lower dissolution of manganese (2%) and dissolution of copper in the range of 70%. This condition represents the lowest extraction achieved.

Influence of copper minerals on cyanide leaching of gold

In elucidating the influence of copper minerals on cyanide leaching of gold, copper minerals were classified into two types according to their solubility in cyanide solutions by proposing two concepts, cyaniding easily soluble copper (E Cu) and cyaniding insoluble copper. The former involves copper occurrence in metal, oxides and secondary
