·The low Cu WF3 Zone 2 and high Cu WF 3 Zone 1 ore samples head grades are shown in Table 1 the high Cu ore being characterized by higher Cu and lower Pb grades than the low Cu economic value calculations showed that value in the low Cu ore was contained largely in sphalerite 67% Zn and galena 29% Pb whereas for the high Cu ore it
·The major recoverable elements of the ore are Pb and Zn with the contents of % and % respectively while Cu with grade of % and Ag with grade of 57 g/t are recovered by enrichment in the Pb concentrate The tailings produced after Pb and Zn beneficiation were used to recover sulfur by combined gravity flotation process
·Lead Pb and zinc Zn are common base metals widely used in modern industrialization Due to their incompatible geochemical properties Pb Zn tends to partition and accumulate in Earth s crust Gao et al 1998 Hofmann 1988 Galena PbS and sphalerite ZnS two essential Pb Zn ore minerals occur in several sediment hosted and
·The imbalance between raw materials of high economic importance and their supply has increased the search for new approaches to obtain valuable elements from mining tailings In this study the extraction of copper zinc and lead from sulfidic tailing in sulfate chloride media was investigated A 33 Box Behnken design was applied to evaluate
