Separation of cobalt and nickel from chloride leach solution of nickel .

In order to separate Ni and Co from the chloride leach solution of laterite ores with high Fe content, solvent extraction and stripping experiments were performed. Various extractants, such as cationic extractants (Cyanex 272 (di(2,4,4-trimethylpentyl)phosphinic acid)), D2EHPA (di-2-ethylhexyl phosphoric acid), Versatic 10 (a.

Cobalt-Nickel Separation in Hydrometallurgy: a Review*

Corefco, the nickel and cobalt refining arm of the Metals Combined Enterprise, operates the nickel refinery in .ort Saskatchewan, Al- berta, Canada which was constructed by Sher- ritt Gordon Mines in 1954. Redevelopment of the operating processes has led to a new process flowsheet and a new cobalt-nickel separation.

Nickel processing | Britannica

The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in.

Nickel: smelting, producing-Metalpedia

Recent advances in hydrometallurgical techniques have resulted in significant nickel purification using these processes. Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction. In hydrometallurgical processes, nickel sulfide ores.
