While there are over 45 different nickel minerals, only a few of them are of economic importance to the minerals industry. The principal nickel mineral in nickel sulphide ores is pentlandite ((Ni,Fe)8S9) while the less common nickel sulphides include millerite (NiS). violarite (Ni2FeS4), polydymite (Ni3S4), siegenitc {(Co,Ni)3S4), and heazlewoodite (Ni3S2).

Pentlandite is an important ore of nickel. However, it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite, chalcopyrite and pyrrhotite in basic igneous rock intrusions. These sulfide ore bodies are probably produced through magmatic segregation.

Mineral Commodity Report 10 — Nickel by Tony Christie and Bob Brathwaite Institute of Geological and Nuclear Sciences Ltd Discovery and Origin of Names The name nickel is derived from the German nickel, meaning Satan or Old Nick's, and from kupfernickel for Old Nick's copper, the mineral niccolite.
Pentlandite, nickel iron sulphide, is the principal ore for nickel. Pentlandite is found in the form of massive granular aggregates. It appears as a brassy goldcolored mineral, having similarities in characteristics to other sulfide minerals like pyrrhotite and chalcopyrite.
