Pentlandite is an iron-nickel sulfide, (Fe,Ni) 9 S 8. Pentlandite usually has a Ni:Fe ratio of close to 1:1. It also contains minor cobalt. It is named after the Irish scientist Joseph Barclay Pentland (1797-1873), who first noted the mineral. Pentlandite forms isometric crystals, but is normally found in massive granular aggregates. It is ...

Pentlandite and chalcopyrite recoveries obtained from this ore at pH 10 are shown as a function of time in Fig. 7, Fig. 8, respectively. In sharp contrast to the case with the Sudbury ore, the pentlandite in this complex sulfide ore is completely depressed in the presence of lime while it reaches high levels of recovery in the soda ash system.
Under mantle and crustal conditions, these elements behave as highly chalcophile elements, and pentlandite (Pn) is an important host for most of these elements. Therefore, understanding how Pn forms is important to understanding the processes that control these elements. The classic model for the formation of Pn is that below 650 °C, …
