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 ...

The difference between production and resources is due mainly to the difficulty associated with processing laterite compared to sulfide ores – leading to a historical preference for sulfide ores. To meet future

Lateritic nickel ore deposits - Wikipedia

Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
