Nickel processing | Extraction & Refining Techniques

The 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 S 3. Some gold, silver, and the ...

Attempts at the beneficiation of lateritic nickel ore

The preconcentration of nickel (Ni) laterite ores ahead of Ni recovery by hydrometallurgical processing makes good economic sense. Since Ni-bearing minerals are often finely disseminated through laterite ores, liberation of minerals either high and/or low in Ni content is a prerequisite prior to any form of separation process.
