Prediction of flotation efficiency of metal sulfides using

Jun 08, · Sulfide ore samples of Mississippi valley type (MVT) were obtained from a mine located in North America. The sulfide ore samples were comprised of galena (PbS), sphalerite (ZnS), pyrite (FeS 2), chalcopyrite (CuFeS 2), and dolomite (CaMg[CO 3] 2). Silicate minerals such as quartz, muscovite, and KFeldspar were also present in trace amounts.

Mineralogy of Sulfides Elements GeoScienceWorld

Sulfide surface chemistry is particularly important because of its relevance to the oxidation and breakdown of sulfide minerals and to the processing of mined ores using froth flotation or leaching. Investigations using spectroscopic and imaging studies of pristine surfaces in ultrahigh vacuum (UHV) conditions have provided information on structure and reactivity at an atomic resolution.
