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 …

Mineralogical analysis showed that the ore had a low base metal sulfide (BMS) content; pyrrhotite (45%), pentlandite (35%) and chalcopyrite (17%) being the major constituents with minor traces of pyrite. The major gangue minerals are plagioclase, enstatite, hornblende and talc, a naturally floating alteration gangue which dilutes the …

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 samples were acid-washed in 0.1 M hydrochloric acid (HCl) solution for 6 h to remove any oxidation layer, rinsed with deionized (DI) water, freeze-dried for 48 h, and stored in a –80 °C freezer. The solid samples were initially crushed and pulverized using a BB 200 jaw crusher and a DM 200 disc mill to reduce the particle size.
