NICKEL AND COBALT ORES: FLOTATION

2016-6-7  Most of the world’s nickel is extracted from themineral pentlandite, (Ni, Fe)9S8, which frequently oc-curs in ores containing predominantly pyrrhotite andvarious non-sulRdes, some of which contain magne-sium (Table 1). The nickel content in such sulRdeores is generally low (0.2}3%) and varies from placeto place in the same deposit. The low nickel contentof the present-day nickel sulRde ores renders themunsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation.The usual method of nickel extraction from sulRdeores is through the production of nickel matte afterenriching the nickel content of the ore. This is com-monly carried out by magnetic separation, Sotation,or a combination of both after the ore
