Recovery from laterite ores. Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions.

Cobalt is a ferromagnetic metal with a specific gravity of 8.9. The Curie temperature is 1,115 °C (2,039 °F) and the magnetic moment is 1.6–1.7 Bohr magnetons per atom. Cobalt has a relative permeability two-thirds that of iron. Metallic cobalt occurs as two crystallographic structures: hcp and fcc.The ideal transition temperature between the hcp and fcc structures is 450 °C (842 °F ...

Nicholson reveals that Chemaf has invested in the construction of a 20 000 tpa cobalt and 16 000 tpa cobalt processing plant on site which when operational within the next year will enable an increase in mining production and also a reduction in operating costs associated with ore transportation – "The project's overall economics could lift significantly at this stage."

Cobalt is almost always a by- or co-product of mining for other base metals, chiefly nickel and copper. Large quantities of cobalt also occur on the sea floor, contained within manganese nodules and cobalt-rich crusts, although they are not economically viable with current technology and economic conditions.

A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.
