ABSTRACT A considerable difference exists between the flotation separation of artificial minerals and real low-grade ores processing where selectivity would be the main issue. Nanobubble-assisted (NB) flotation investigations have been mostly examined with pure materials and a narrow particle size range, less on complex sulfide ores. This study considered NB …

The Huangshaping W–Sn–Pb–Zn and Cu–Pb–Zn skarn mineralization systems have formed multi-types of pyrite in the calcite-sulfide and siderite-sulfide stages, which are inferred to have hydrothermal origins based on their high As/Ni ratios (9.82–36,061) and coexistence with hydrothermal minerals (calcite, siderite, sericite, fluorite ...

In this research, flotation of copper, lead and zinc minerals from a copper oxide–sulfide ore was studied. The identification tests showed that the sample is a mixture of quartz, chalcopyrite, galena, cerussite, hemimorphite and iron oxide minerals with 5.04% CuO, 1.61% PbO, 2.07% ZnO and 56.40% SiO2. The experimental design methodology (RSM) was …

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 …

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). Ore fabrics and mineral assemblages of Cu and Pb-Zn ...
