In general, Ni production from sulfide ores involves either open cut or underground mining, followed by concentration via flotation, smelting of concentrates to produce a Ni (± Cu) matte, then refining to produce a pure metal. It is common for mines, smelters and refineries to be in different locations, depending on regional geographic factors.

Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.
