    www.britannica.com/science/pentlandite 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: The mineral pentlandite information and pictures

    www.minerals.net/mineral/pentlandite.aspx Pentlandite is both an individual mineral, and the name of a mineral group. The Pentlandite group is composed of rare sulfides that have similar chemical structures, with Pentlandite being the most prominent member of the group. Pentlandite is named in honor of Joseph Barclay Pentland (1797–1873), a natural scientist from Ireland who first identified this mineral.
  • Pentlandite - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/engineering/pentlandite The extractable sulfide minerals are pentlandite ((Ni,Fe) 9 S 8) which contains a small amount of cobalt, and the most abundant pyrrhotite ((Fe n−1 S n) or (Ni,Fe) 7 S 8). Chalcopyrite is another major mineral for nickel sulfide ores that must be considered when choosing extractive processes.

  • PENTLANDITE (Iron Nickel Sulfide) - Amethyst Galleries

    www.galleries.com/pentlandite 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.
