Processing considerations for cobalt recovery from …

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.
