Minerals of Ni-S, Fe-S and Fe-Ni-S systems were investigated by Geiger counter X-ray spectrometer in order to clarify the mineral composition of crude nickel matte produced by fusion of garnielite, gypsum and limestone with coke.
In Ni-S system the compound Ni3S2 and NiS, and in Fe-S system the compound FeS were formed as sulphides. In Fe-Ni-S system a compound pentlandite was formed in the range of 4.5 Fe.4.5Ni·8.9-5Fe·4Ni·8S. When the product contained much more Fe component, FeS was formed together with pentlandite and Ni·Fe solid solution. When the nickel content of the product was much more than the above range, Ni3S2, pentlandite and nickel rich Ni·Fe solid solution were formed.
It was clarified that the crude nickel matte containing 58-% of Fe, 22% of Ni and 18% of S consisted of FeS, nikel rich Ni·Fe solid solution and small amount of pentlandite. The matte containing 62% of Fe, 21% of Ni and 15% of S was composed of FeS and Ni·Fe solid solution.
