A New Process for Cobalt Nickel Separation

31 Basic Process for Cobalt Separation from Nickel CSIRO have developed a number of solvent extraction processes to separate nickel and cobalt (together) from other elements present in solution such as zinc and manganese This technology uses a synergistic combination of two or more extractants, and is thus known as SSX The new process developed by CESL and CSIRO uses SSX for the

Hydromet Technology Vale

The new hydrometallurgical process that Vale developed will process the nickel concentrate directly to metal products without first having to smelt the concentrate The concentrate will be processed in a pressurized vessel where it will react with oxygen and sulphuric acid to produce an impure solution of nickel, cobalt and copper This solution will pass through a number of chemical
