Mineral chemistry of sphalerite and galena from Pb
Fe and Cd constitute the two most important minor constituents in sphalerite from the Ghaap Plateau Average concentrations vary between 054 weight % and 321 weight % for Fe and 013 weight % and 067 weight % for Cd to CuO and CuS The oxidation of galena and sphalerite proceeds according to a linear rate law: that of chalcocite leads to the formation of a coherent product layer impenetrable to Oz and HrO vapor Keywords: air oxidation, oxidation products, sulfide minerals, galena, sphaleriteOXIDATION OF SULFIDE MINERALS V GALENA, Oxidation of sulfide minerals; V, Galena, sphalerite and chalcocite Energy, Mines Resour Can, CANMET, Ottawa, ON, Canada The Canadian Mineralogist (1980) 18 (3): 365–372 H F Steger, L E Desjardins; Oxidation of sulfide minerals; V, Galena, sphalerite and chalcociteOxidation of sulfide minerals; V, Galena, sphalerite and
