Pentlandite is the principal host for the bulk of the cobalt in the Sudbury ores Naldrett, 1961, and there is a range in Ni/Co ratio depending on whether the pentlandite was formed in a contact or footwall environment Lightfoot, 2015 . Some cobalt exists in solid solution in pyrrhotite, and the Ni/Co ratio of pyrrhotite + pentlandite rich

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 have isometric symmetry. For chemical formula and detailed physical properties, see sulfide

Abstract The use of pyrrhotite containing aggregate in concrete has led to the premature deterioration of building foundations in Connecticut U.S.A. . Pyrrhotite is a highly reactive iron sulfide mineral that can initiate internal sulfate attack in concrete structures, because it serves as a source of sulfate ions for secondary minerals. Get Price

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.

What is barite used for? Barite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for x ray shielding. Barite has the ability to block x ray and gamma ray emissions. Barite is used to make high density concrete to block x ray emissions in hospitals, power plants, and laboratories.
