nickel production methods from pentlandite oxide ores

The nickel extraction process is dictated by the mineralogical assemblage of the sulphide and oxide nickel ores from which it occurs. The rejection of pyrrhotite, which occurs commonly with pentlandite, has been of no real importance in many mills treating sulphide ores except in countries having strict restrictions on SO2 emission.
