Copper Nickel Arsenides Mohawk, Mi
An objection may be raised that the copper arsenides were in fact derived from the action of initially arsenic-poor fluids upon the nickel arsenide, and the adjoining copper in the wall rocks. This appears to be quite unlikely since the relative quantities of nickel arsenides encountered during mining operations throughout the Keweenaw Peninsula were insignificant with respect to the copper arsenides.

Chapter 16: Flotation of Nickel and Nickel Copper
Nickel minerals can be divided into three major groups, including nickel sulfides, nickel arsenides and nickel antimonides, normally the minerals of magmatic and hydrothermal origin, nickel silicates and other similar compounds. From the sulfide minerals, the most abundant are pentlandite, rloanlit and nickelin.

The geology and mineralogy of host metamorphic rocks, the mineralogy of sulfide ores, and the distribution of PGE mineralization were studied in detail for the Kvinum-1 and Kvinum-2 copper-nickel occurrences of the Kvinum ore field, which are the most promising targets for the copper-nickel-PGE mineralization of the Sredinny Range of Kamchatka. It was established that stringer-disseminated and ...

Nickeline (Nickel Arsenide)
Its first name was the German term "Kupfer nickel" or copper nickel. It sounds like some sort of alloy. It actually was a term of derision because nickel meant "nixes" or underground goblins. The miners in Germany who first saw the copper-red metallic mineral were convinced the mineral was a rich ore of copper.

2021-5-4 Nickel was first discovered by Alex Constedt in 1751. The nickel atom has a radius of 124 pm and a Van der Waals radius of 184 pm. In its elemental form, nickel has a lustrous metallic silver appearance. Nickel is a hard and ductile transition metal that is considered corrosion-resistant because of its slow rate of oxidation.
