Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.

Handbook of Flotation Reagents ScienceDirect

The flotation process is governed by a complex phenomenon occurring on the surface of mineral particles and air bubbles formed in the water phase. From the practical point of view, the hydrophobicity and bubble mineralization are perhaps the two most important factors in flotation and govern the system kinetics and selectivity of flotation.
