Oxides include laterite, where the principal mineral mixtures are nickeliferous limonite, (Fe,Ni)O(OH), and garnierite (a mixture of various hydrous nickel and nickel-rich silicates). [36] Nickel sulfides commonly exist as solid solutions with iron in minerals such as pentlandite and pyrrhotite with the formula Fe 9-x Ni x S 8 and Fe 7-x Ni x S ...
Kamacite is an alloy of iron and nickel, which is found on Earth only in meteorites.According to the International Mineralogical Association (IMA) it is considered a proper nickel-rich variety of the mineral native iron.
As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [38] With sodium, the double sulfate is nickelblödite Na 2 Ni(SO 4) 2 · 4 H 2 O from the blödite family. Nickel can be substituted by other divalent metals of similar sized to make mixtures that crystallise in the same form. [39]

Nickeline or niccolite is the mineral form of nickel arsenide. The naturally-occurring mineral contains roughly 43.9% nickel and 56.1% arsenic by mass, but composition of the mineral may vary slightly. [2] Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony.
Garnierite is a general name for a green nickel ore which is found in pockets and veins within weathered and serpentinized ultramafic rocks. It forms by lateritic weathering of ultramafic rocks and occurs in many nickel laterite deposits in the world. It is an important nickel ore, having a large weight percent NiO.
The nickel sulfide with simplest stoichiometry is NiS, also known as the mineral millerite. From the economic perspective, Ni 9 S 8, the mineral pentlandite, is the chief source of mined nickel. Other minerals include heazlewoodite (Ni 3 S 2) and polydymite (Ni 3 S 4), and the mineral Vaesite (NiS 2). [1] Some nickel sulfides are used ...
Gersdorffite or Nickel glance (trivial name) is a nickel arsenic sulfide mineral with formula NiAsS. It crystallizes in the isometric system showing diploidal symmetry. It occurs as euhedral to massive opaque, metallic grey-black to silver white forms. Gersdorffite belongs to a solid solution series with cobaltite, CoAsS.
