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. Then ...

Enhanced methods for nickel recovery from low-grade ores ...
Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals. Mining nickel directly is the obvious route to obtaining pure nickel, however, nickel can also be recovered as a byproduct of other metals.
