The effect of mode of occurrence of galena and sphalerite
The occurrence of galena locked and/or attached to sphalerite increased with increasing particle size, especially for particles larger than 50 micron in diameter Thus, the poorly liberated sphalerite particles from the middlings would contribute to the problem of zinc deportment into the lead concentrate at the Rosh Pinah MineTHE EFFECT OF MODE OF OCCURRENCE OF GALENA AND SPHALERITE ON THE SELECTIVE FLOTATION OF ORE SAMPLES FROM THE ROSH PINAH MINE Makunga Daudet Seke* and Petrus Christiaan Pistorius Department of Materials Science and Metallurgical Engineering, University of Pretoria, Pretoria 0002, South Africa ABSTRACT The flotation response of a PbZn sulphide ore from THE EFFECT OF MODE OF OCCURRENCE OF GALENA AND Occurrence Galena occurs in a number of environments, such as hydrothermal veins (formed under various temperatures), metamorphic deposits, and in pegmatites Limestones and dolostones are common in host rocksGalena Mineral Physical Optical Properties, Occurrence Sphalerite and Galena Occurrence Z84 Occurrence: Occurrence: Newton Co County: Indiana: State: USA: Country: This page is currently not sponsored Click here to sponsor this page Photos Maps Standard Add Photo Map Pages Nearest Localities Use Map in Article Mineral Similar Localities Nearest Localities Possible Missing Minerals Google Link to USGS Key Latitude Sphalerite and Galena Occurrence Z84 Occurrence, Newton Co Mineral Group: Sphalerite group Occurrence: Formed under a wide range of low to hightemperature hydrothermal conditions; in coal, limestone, and other sedimentary deposits Association: Galena, chalcopyrite, marcasite, pyrite, fluorite, barite, quartz, many other hydrothermal minerals Distribution: The most important ore of zinc Only a Sphalerite (Zn Fe)S Handbook of Mineralogy
