Nickel is a silvery-white metal that is used mainly to make stainless steel and other alloys stronger and better able to withstand extreme temperatures and corrosive environments. Nickel was first identified as a unique element in 1751 by Baron Axel Fredrik Cronstedt, a Swedish mineralogist and

Nickel resists corrosion and is used to plate other metals to protect them. It is, however, mainly used in making alloys such as stainless steel. Nichrome is an alloy of nickel and chromium with small amounts of silicon, manganese and iron. It resists corrosion, even when red hot, so is used in toasters and electric ovens. A copper-nickel alloy is commonly used in desalination plants, which ...

Pentlandite is the most common terrestrial nickel sulfide. It typically forms during cooling of a sulfide melt. These sulfide melts, in turn, are typically formed during the evolution of a silicate melt.
Pentlandite is a rather pale brassy yellow metallic sulphide, one of the most important nickel ores, and a primary mineral in many ultramafic rocks. It usually found associated, and commonly finely intergrown, with pyrrhotite, and rarely shows microscopically visible crystals.
These deposits can consist of a variety of metallic minerals containing valuable metals such as nickel (pentlandite), copper (chalcopyrite), zinc (sphalerite), lead (galena) and gold (occurs as a native element or as a minor constituent within other minerals) that are used in all aspects of our daily lives.
Pentlandite 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.
…most important nickel mineral is pentlandite, (Ni, Fe) 9 S 8, followed by pyrrhotite, usually ranging from FeS to Fe 7 S 8, in which some of the iron may be replaced by nickel. Chalcopyrite, CuFeS 2, is the dominant copper mineral in these ores, with small amounts of another copper mineral, cubanite, CuFe 2 …
Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on earth, and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.
The principle nickel sulphide is pentlandite (NiFeS2), which is usually associated with chalcopyrite and iron sulphides. International Nickel (INCO) and Sherritt Gordon use a bulk Cu/Ni float pictured below, followed by selective flotation of the two elements into separate concentrates. Other Canadian producers leave separation to the smelters.
pentlandite (pĕnt´ləndīt), yellowish-bronze, opaque mineral, a sulfide of iron and nickel, (Fe,Ni) 9 S 8. It is found in masses nearly always associated with the iron sulfide pyrrhotite. The largest deposit of this important ore of nickel is at Sudbury, Ont. Important deposits are …

pentlandite - a mineral (iron and nickel sulphide) that is the chief ore of nickel atomic number 28, Ni, nickel - a hard malleable ductile silvery metallic element that is resistant to corrosion; used in alloys; occurs in pentlandite and smaltite and garnierite and millerite
Pentlandite has a metallic luster, a light bronze-yellow color, a hardness on Mohs' scale of 3–4, and a density of 4,500–5,185 kg/m 3. It occurs in the form of massive or granular aggregates in sulfide-ore deposits genetically associated with basic and ultrabasic igneous rocks, such as gabbro-norites and pyroxenites. Pentlandite is one of the principal minerals of nickel ores.
