how are nickel minerals processed

Nickel processing | Britannica.com

Canadian ores are sulfides containing nickel, copper, and iron. The most important nickel mineral is pentlandite, (Ni, Fe)9S8, followed by pyrrhotite, usually ranging from FeS to Fe7S8, in which some of the iron may be replaced by nickel. Chalcopyrite, CuFeS2, is the dominant copper mineral in these ores, with small...

Nickel: An introduction - Explain that Stuff

Aug 5, 2017 ... Nickel has featured in alloys (such as cupronickel, used in coins) for thousands of years, but it was recognized as a chemical element in its own right only in 1751. That was when Swedish chemist BXinhai Axel Frederic Cronstedt (1722–65) first isolated pure nickel from a reddish ore (mineral-containing rock)...

Nickel - Wikipedia

Use of nickel (as a natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes...

Nickel is one of the three ferromagnetic metals (with iron and cobalt), but is weakest of the three. Nickel is very common in meteorites, and its presence often determines if a stone is a meteorite or not. Most nickel is used in alloys with steel, especially stainless steel. It is also used in catalysts and as a plating to protect other,...

USGS Minerals Information: Nickel

Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel. Another 12% goes into superalloys (e.g., Inconel 600) or nonferrous alloys (e.g., cupronickel). Both families of alloys are widely...
