Recovery of iron from lead-zinc metallurgical slags by bath smeltingLIU Qun(刘群)1, WANG Chong-qing(王重庆)1, TAN Jun(谭军)1, YIN Zhou-lan(尹周澜)1, CHEN Qi-yuan(陈启元)1, LIAO Zhou(廖舟)2, ZHANG Ping-min(张平民)1..., China)Abstract:The recovery of iron from iron sinking slag and lead smelter slag was investigated by desulfurization-reduction bath smelting. The effects of lead smelter slag (LSS) to iron sinking......
-forming mechanism and ore-forming mechanism of the deposit were discussed according to the study of lead isotope as well as chemical analysis, including whole-rock analysis,REE analysis and trace... the source of crust-mantle mixed deep in the earth. The REE studies of wall rocks indicate the seawater involved in diagenesis and the deposit with characteristics of exhalative sedimentary deposit. The lead......
