Pentlandite - an overview | ScienceDirect Topics

The fraction of nickel in pentlandite (nickel ore) is only 5.5 × 10 −3 g Ni/g ore. To supply 1 g of pure nickel to an industrial process requires that at least 181 g of pentlandite be dug. If the nickel mine is underground, the upper layers of topsoil and clay are also excavated, perhaps a forest is also cut and biotic material degraded.

Pentlandite | mineral | Britannica

Pentlandite, a nickel and iron sulfide mineral, the chief source of nickel. It is nearly always found with pyrrhotite and similar minerals in silica-poor rocks such as those at Bushveld, S.Af.; Bodø, Nor.; and Sudbury, Ont., Can. It has also been found in meteorites. Pentlandite forms crystals

(PDF) The effect of sodium metabisulfite and

Although pentlandite in these ores is 5–15 times less abundant than pyrrhotite, it is the main nickel bearing mineral containing up to 36% Ni by weight while carrying about 33% sulphur. Considering these percentages, it can be estimated that, per unit weight of nickel, there is about 44 times more sulphur associated with pyrrhotite than with .
