sulphide ores nickel

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 SherrittGordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.
