nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 °F) and a ...

The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed. NiS + 2O2 NiSO4. CoS + 2O2 CoSO4.

The choice of mining method for nickel extraction depends on several factors, including the deposit type, location, depth, and ore characteristics. The two primary mining methods used for nickel extraction are: 1) Open-Pit Mining: Open-pit mining is the most common method used for nickel mining, especially for large, near-surface deposits.
