Copper-Nickel ores

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

NICKEL AND COBALT ORES : FLOTATION | Semantic Scholar

Most of the world's nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ...
