Sulfide Ores - an overview | ScienceDirect Topics

The source of the sulphur in these ore bodies is either from the magma itself or from the pre-existing rock where it was present as sulphate. The most common nickel mineral in these ores is pentlandite, (Ni,Fe) 9 S 8. The atomic ratio of nickel to iron in pentlandite ranges between 0.34 and 2.45. Most often, though, it is about 1.15.
