Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore.
Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace , and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy.
Cobalt is only extracted alone from the Moroccan and some Canadian arsenide ores. It is normally associated as a by-product of copper or nickel mining operations. Around 55% of the world cobalt production comes from nickel ores.
As the copper and nickel ions remain inside the system and, additionally, the amount is very small Table 4 – life cycle inventory outputs , considered as a unit process with 100% allo ion to cobalt Westfall, Davourie, Ali, and Macgough, 2016 .
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.

Cobalt is a ferromagnetic metal with a specific gravity of 8.9. The Curie temperature is 1,115 C 2,039 F 5 and the magnetic moment is 1.6–1.7 Bohr magnetons per atom. 6 Cobalt has a relative permeability two-thirds that of iron. 7 Metallic cobalt occurs as two crystallographic structures: hcp and fcc..

The segregation process has been known for many years and applied industrially for the treatment of various refractory copper ores. The principles of the process are briefly reviewed; the process was tested in the laboratory on two copper-cobalt oxide ores from Gecamines, Shaba Province, Zaire. Various parameters of the process, such as segregation temperature, dosage of reducing and ...

In 1864 cobalt ore was discovered in New Caledonia and the European cobalt mining industry declined. In 1904 cobalt deposits were found in Canada – this further affected Europe. After the discovery of large cobalt deposits in the Congo was made in 1914 the industry shifted yet again, this time with focus on the DRC.

An oxide ore or ore concentrate of nickel, cobalt or copper is beneficiated by means of a vapour phase process. The beneficiation is enhanced by increasing the level of the active iron oxide content to a level higher than that contained in the starting material.
