A review on process-related characteristics of pyrrhotite
MetadataShow full item record
In this review, the physical and chemical properties of the pyrrhotite group minerals are discussed, particularly their mineralogical behavior during mineral processing and phase transitions. Pyrrhotites are often associated with nickel ores and gold deposits. Consideration of the leaching processes of pyrrhotites focuses on the recovery of Ni and Au. The mechanisms of acid leaching are presented from physical, chemical, electrochemical, and crystallographic viewpoints. Other pyrrhotite processing techniques, including oxidation and flotation, are also included in this article.

Relationship between microstructures and grain-scale trace element distribution in komatiite-hosted magmatic sulphide oresVukmanovic, Zoja; Reddy, Steven; Godel, B.; Barnes, S.; Fiorentini, M.; Barnes, S.; Kilburn, M.R. (2014)Komatiite-hosted nickel sulphides from the Yilgarn Craton (Australia) consist of two main sulphide phases: pyrrhotite (Fe7S8) and pentlandite ((Fe,Ni)9S8); two minor sulphide phases: chalcopyrite (CuFeS2) and pyrite (FeS2) ...
In situ multiple sulfur isotope analysis by SIMS of pyrite, chalcopyrite, pyrrhotite, and pentlandite to refine magmatic ore genetic modelsLaFlamme, C.; Martin, L.; Jeon, H.; Reddy, Steven; Selvaraja, V.; Caruso, S.; Bui, T.; Roberts, M.; Voute, F.; Hagemann, S.; Wacey, D.; Littman, S.; Wing, B.; Fiorentini, M.; Kilburn, M. (2016)With growing interest in the application of in situ multiple sulfur isotope analysis to a variety of mineral systems, we report here the development of a suite of sulfur isotope standards for distribution relevant to ...
Cu–(Ni–Co–Au)-bearing massive sulfide deposits associated with mafic–ultramafic rocks of the Main Urals Fault, South Urals: Geological structures, ore textural and mineralogical features, comparison with modern analogsMelekestseva, I; Zaykov, V; Nimis, P; Tret'yakov, G; Tessalina, Svetlana (2013)Cu-rich massive sulfide deposits associated with mafic–ultramafic rocks in the southern portion of the Main Urals Fault (MUF) are characterized by variable enrichments in Ni (up to 0.45 wt.%), Co (up to 10 wt.%) and Au ...
