COBALT PROCESSING DEVELOPMENTS K G Fisher …
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

Optimization of the flotation of copper smelter slags from ...
All these three furnaces produce fayalite slag as a byproduct. The slags contain copper with the content ranging between 0.8 to 5% copper. The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant (Slag Mill Plant) for liberation and recovery of copper.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
