sophoclesno smelter in thw orld would touch 80% pyrrhotite deposit because of high iron content.
wasn't that how Voisey's Bay was discovered, a big red gossan.
i guess inco has a big problem then.

At Voisey's Bay the ore consists of, approximately : 75% pyrrhotite, FeS; 12% pent-landite, Fe,Ni9S8; 8% chalcopyrite, CuFeS2; and 5% magnetite Fe3). The last droplets of sulphide liquid that separated will be trapped by the crystallizing gabbroic magma as disseminated sulphide ore overlying the massive sulphides at the bottom of the magma chamber (Figures and ).
