NICKEL AND COBALT ORES: FLOTATION

curs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magne-sium (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 ores renders them
