Pyrrhotite flotation and its selectivity against

Abstract. Pyrrhotite (Po) is one of the most abundant sulfide minerals in processing industry and must be rejected in most cases. Particularly, Po rejection and its selectivity against pentlandite (Pn) have long been a challenge due to similarities in the mineral composition of the two minerals and the collectorless flotation characteristics of Po.

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

The nature of the mineralization of these ores is such that the natural pH of the ore slurries is always alkaline, at a pH of around 9. The PGEs are recovered by flotation and the flotation of the BMS is treated as a bulk
