Flotation of Copper oxide ore - Fodamon Machinery

For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper oxide is easy to float, and copper oxide can not be recovered by a single flotation method. Copper oxide minerals in a separate state are called free ...

COBALT PROCESSING DEVELOPMENTS K G Fisher Bateman ... -

The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – e.g. the Kolwezi Tailings Project. Similarly, because cobalt follows iron during smelting, some of the copper smelter
