Efficient extraction of cobalt and copper: Leveraging redox …
Copper-cobalt ores typically contain cobalt ranging from 0.01 to 0.8 %, and their coexistence with copper results in a complex mineral composition [6].After flotation, it is feasible to separate the ore into copper-cobalt oxide and sulfide concentrates [7].The oxide concentrates primarily contain copper and cobalt in the forms of malachite, azurite, and heterogenite [8], [9].

Distinctive composition of copper-ore-forming arcmagmas
Accumulation of dissolved H 2 O through multiple cycles of replenishment and crystallisation in high-pressure magma chambers can explain the distinguishing chemical features of copper-ore-forming calc-alkalic arc magmas. The distinguishing features include unusually high contents of Sr and V, and unusually low contents of Sc and Y.
