Nickel Sulphate Copper Refine

Enhanced methods for nickel recovery from low-grade ores ...

6/9/2017  Classical methods for nickel recovery are precipitation, oxidation, and crystallization. Nickel and sulfate tend to build up in the copper refinery electrolyte and can be removed by crystallization as NiSO 4 6H 2 O crystals from the bleed stream. They are then separated from the mother liquor in a centrifuge, and dried and bagged for shipment.

Refining of crude nickel sulphate obtained from copper ...

A new method of crude nickel sulphate refining for the Copper Smelter at Krompachy (Slovak Republic) was studied. The crude nickel sulphate removed from the copper electrolyte in the tankhouse contains iron, copper, zinc, and cobalt as impurities, mostly in the form of sulphates.

Nickel(II) sulfate - Wikipedia

The salt is usually obtained as a by-product of copper refining. It is also produced by dissolution of nickel metal or nickel oxides in sulfuric acid. Aqueous solutions of nickel sulfate reacts with sodium carbonate to precipitate nickel carbonate, a precursor to nickel-based catalysts and pigments.
