lead zinc ore beneficiation experiment report
BENEFICIATION EXPERIMENT REPORT OF LEAD ZINC ORE 1.ABSTRACT 1.1 A Lead – Zinc sample assaying 8.52% Pb, 6.46% Zn, 0.06% Cu, 22.71% Fe(T), 9.19% S, 25.05% SiO 2 , 6.40% Al 2 O 3 , 4.42% CaO, 5.27% MgO,1.12% Graphitic carbon, 0.04% Ni, 0.01% Co, 0.76% Mn, 0.13% Ti, 0.02% Cd was undertaken for bench scale beneficiation studies in Ore Dressing Laboratory of sinoninetech. 1.2 The object of the bench scale investigation was to develop process flowsheet to produce individual lead and zinc concentrates suitable for end use industries 1.3 Mineralogical studies on the sample reveal that the sample consists of carbonates viz. calcite, siderite, dolomite and quartz with subordinate amount of clay, sphalarite, galena, minor amount of feldspar (plagioclase, orthoclase), while talc, goethite/limonite, pyrite, graphite, chalcopyrite, hematite and pyroxene (diopside) are noticed in very minor to trace amount. 1.4 In order to produ...
