Cobalt in the form of heterogenite is commonly associated with copper bearing oxide ores and hence it is commonly co-extracted with copper. In order to extract cobalt with copper, a reducing environment is created for reduction of Co3+to Co2+as divalent cobalt is soluble at the pH values at which copper dissolution is conducted.

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silicate minerals from quartz to talc and clays.
