The metallurgy of nickel is complicated in its details, many of which vary widely, according to the particular ore being processed. In general, the ore is transformed to dinickel trisulfide, Ni 2 S 3 (with nickel in the +3 oxidation state), which is roasted in air to give nickel oxide, NiO (+2 state), which is then reduced with carbon to obtain the metal.

Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Consequently, mining and smelting ore are the major industries. Norilsk is the center of a region where nickel, copper , cobalt , platinum , palladium and coal are mined. Mineral deposits in the Siberian Craton had been known for two centuries before Norilsk was founded, but mining began only in 1939, when the buried portions of the Norilsk,
