In this contribution, S and Pb isotopic measurements were carried out for the Baoshan Cu–Pb–Zn deposit. Combined with the systematic analyses of previously published S and Pb isotopic data of the major granite-related Cu–Pb–Zn deposits and geochemical data of the host rock granitoids in the Qin–Hang ore belt, this study aims to provide geochemical …

For the high-Cu ore, the challenge was to produce three distinct Cu, Pb, and Zn concentrates. Whilst the initial approach of exploiting relative flotation kinetics using the current RPZC operating conditions did not achieve the desired Cu-Pb selectivity, a feasible flowsheet was developed based on a modified Black Mountain (Cu-Pb-Zn concentrator) processing route for …

Zn, Pb, Ga and Ge were separated and recovered from zinc refinery residues by stepwise leaching. In the first stage, by leaching with H 2 SO 4 media, more than 90% of Zn and 99% of Ga were dissolved, leaving 92% of Ge in the leaching residue. In the second stage, by leaching with HCl media, approximately 99% of Pb and less than 2% of Ge were selectively …

In the main stage Cu-Pb-Zn mineralization, Cu was precipitated prior to Pb and Zn. The Cu mineralization in the mylonites is dominated by stockworks while breccia mineralization is common in Pb-Zn ores and the fragments are cemented by sphalerite, galena, and pyrrhotite (Zhong et al., 2012).
