The literature has explored techniques to filter and separate nickel and cobalt product derivatives from laterites. Many techniques have been mentioned in the literature (Table 10), such as solvent extraction using solvents. Nickel is dissolved mainly while cobalt and manganese are stabilized in the solid phase by preferential oxidation.

There appeared a close relationship between the oxidation of pyrite and the extraction of cobalt, confirming that cobalt presents as an iron substitute in pyrite lattice. It can be concluded from these findings that the H 2 SO 4 -NaNO 3 leaching system is a promising alternative to extract cobalt from cobaltiferrous pyrite concentrates/tailings.
Finally, various solvent extraction techniques for the extraction and separation of cobalt and nickel using Cyanex extractants were discussed as well as newer processes of extraction and separation.
If copper and cobalt-containing ores are processed, solvent extraction is the most effective method for separation. In this case, since copper is the main mineral, the aim is to eliminate the cobalt present from the circuit, which ends up in refining together …
