NICKEL AND COBALT ORES: FLOTATION
Most of the world's nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently oc-curs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magne-sium (Table 1). The nickel content in such sul Rde ores is generally low (0.2}3%) and varies from place to place in the same deposit.
