B. Mishra, in Encyclopedia of Materials: Science and Technology, 2001 1 Sources and Commercial Methods. The extractable sulfide minerals are pentlandite ((Ni,Fe) 9 S 8) which contains a small amount of cobalt, and the most abundant pyrrhotite ((Fe n−1 S n) or (Ni,Fe) 7 S 8).Chalcopyrite is another major mineral for nickel sulfide ores that must be considered when choosing extractive processes.

Pentlandite Wikipedia

Pentlandite is an iron–nickel sulfide, (Fe,Ni) 9 S 8.Pentlandite has a narrow variation range in Ni:Fe but it is usually described as having a Ni:Fe of 1:1. It also contains minor cobalt, usually at low levels as a fraction of weight.. Pentlandite forms isometric crystals, but it is normally found in massive granular aggregates.It is brittle with a hardness of 3.5–4 and specific gravity of

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Jul 28, 2019· Production . Nickel is primarily extracted from the nickel sulfides pentlandite, pyrrhotite, and millerite, which contain about 1% nickel content, and the iron-containing lateritic ores limonite and garnierite, which contain about 4% nickel content. Nickel ores are mined in 23 countries, while nickel is smelted in 25 different countries.
