Pentlandite an overview | ScienceDirect Topics

The fraction of nickel in pentlandite (nickel ore) is only 55 × 10 −3 g Ni/g ore To supply 1 g of pure nickel to an industrial process requires that at least 181 g of pentlandite be dug If the nickel mine is underground, the upper layers of topsoil and clay are also excavated, perhaps a forest is also cut and biotic material degradedPentlandite 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 segregationPENTLANDITE (Iron Nickel Sulfide) Amethyst Galleries

The Separation of Pentlandite from Chalcopyrite

In sulfide nickel deposits throughout the world, pentlandite and pyrrhotite are commonly found together along with varying amounts of chalcopyrite and platinum group minerals (PGMs) The mafic or ultramafic host silicates associated with the sulfide mineralisation commonly exhibit a complex assemblage of magnesium bearing silicates, many of which themselves contain significant nickeloremineral phases under the reflectedlight microscope qualitatively with the additional use of etching techniques These systematic studies resulted in the publication of the first edition of Die Erzmineralien und ihre Verwachsungen [The Ore Minerals and their Intergrowths] in 1950 2 Characteristic Physical Properties of Ore MineralsORE MINERALOGY EOLSS
