The world's nickel resources mainly come from nickel sulfide ore and laterite ore. The former accounts for 28% of the world's nickel resources while the latter accounts for 72%. With the shortage of nickel sulfide ore and the increasing demand for nickel, laterite ore has become the main resource for nickel extraction recently.Web

Ores Sulfides. Canadian ores are sulfides containing nickel, copper, and iron. The most important nickel mineral is pentlandite, (Ni, Fe) 9 S 8, followed by pyrrhotite, usually ranging from FeS to Fe 7 S 8, in which some of the iron may be replaced by nickel. Chalcopyrite, CuFeS 2, is the dominant copper mineral in these ores, with small amounts of another …Web

EXTRACTING METALS FROM SULFIDE ORES. Many important metals are present in nature combined with sulfur as metal sulfides; these include cadmium, cobalt, copper, lead, molybdenum, nickel, silver, and zinc. In addition, gold and platinum group metals are associated with sulfidic base metal ores. The extraction of metals from their ores has …Web

Nickel sulphide ore is mined at our open-cut and underground operations in the Northern Goldfields of Western Australia. It is then crushed and concentrated using nickel sulphide flotation technology, before being dried and railed to the Kalgoorlie Nickel Smelter, where it is fed to a flash furnace. This produces a granulated matte product ...Web

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.Web
