Abstract: S and Fe elements were enriched in tailings of Xitieshan Pb-Zn mines. It was beneficial to recover the S and Fe for economy and environment. The process route and characteristics of sulphuric acid and pig iron were presented concisely. The products were produced by using tailings of Xitieshan Pb-Zn mines as raw materials by Qinghai Innovation Mining Development Co. Ltd. The results can be helpful to comprehensive utilization of tailings of other Pb-Zn mines.
