The flotation kinetics of principal ore minerals is shown in Fig. 2.As is evident, the principal ore minerals—pentlandite and chalcopyrite—are characterized by greater floatability than the others and, owing to this, practically all the opened grains and rich aggregates of these minerals pass to the concentrate of between-bath flotation.
Polymorphism & Series: Forms a series with cobalt pentlandite. Mineral Group: Pentlandite group. Occurrence: Commonly intimately associated with pyrrhotite; in ultramafic rocks and perhaps derived from them by magmatic segregation; also found in mantle xenoliths and undersea "black smoker" deposits; rarely in meteorites.
Pentlandite is the dominant Ni-hosting ore mineral in most magmatic sulfide deposits and has conventionally been interpreted as being entirely generated by solid-state exsolution from the high-temperature monosulfide solid solution (MSS) (Fe,Ni) 1–x S. This process gives rise to the development of loops of pentlandite surrounding pyrrhotite grains.

Pentlandite is a mineral consisting mainly of iron-nickel sulfide, in which the ratio of nickel to iron is usually close to 1:1. Its chemical formula is written as (Fe,Ni) 9 S 8.It also contains minor proportions of cobalt.It has a yellowish bronze color. It was named after the Irish scientist Joseph Barclay Pentland (1797-1873), who first noted the mineral.
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.
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 that.
