The Occurrence and Origin of Pentlandite-Chalcopyrite

Abstract 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–xS.

Mineral Deposits

Mineral Deposits, or Mineral Veins, are veins of ores that are very thin but very spread out. They cannot be detected without a Core Sample Drill and cannot be extracted without an Excavator. Each Mineral Deposits takes up only one chunk; this can be in any chunk though, including other dimensions and in void worlds. Most veins are not made of a single material, but made of a mix …

The Occurrence and Origin of Pentlandite-Chalcopyrite-Pyrrhotite Loop

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.

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, the high ...

Millerite (NiS) Serapation from Pentlandite and Chalcopyrite

While there are over 45 different nickel minerals, only a few of them are of economic importance to the minerals industry. The principal nickel mineral in nickel sulphide ores is pentlandite ((Ni,Fe)8S9) while the less common nickel sulphides include millerite (NiS). violarite (Ni2FeS4), polydymite (Ni3S4), siegenitc {(Co,Ni)3S4), and heazlewoodite (Ni3S2).
