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.

Mining and concentrating where you utilise the run of mine ore and put it through a flotation circuit, in turn upgrading the ore from a low-grade concentrate (say 3 % Ni) to a much higher grade (up to 25% in some cases). This allows the miner to reject the majority of the material mined before complex processing takes place, reducing costs.
