A complex lead-zinc sulfide ore from Inner Mongolia Autonomous Region, China, was subjected to this work. Research on mineral processing was conducted according to the properties of the lead-zinc ore. The lead minerals are successfully separated from the zinc minerals with the combination of collectors. Compared to CuSO4, new reagent X-43 as zinc activator shows its advantage in marmatite flotation. With the process utilized in this work, a lead concentrate of 59.67% Pb with a recovery of 78.69% and a zinc concentrate of 50.99% Zn with a recovery of 81.98% are produced. The silver recovery in the lead concentrate is 56.76% while the indium recovery in the zinc concentrate is 42.60%.

The properties of a lead-zinc ore are investigated by XRD and SEM analysis methods. Results show that the ore assays 1.27 per cent Pb and 1.62 per cent Zn, mainly occurring in the form of sulfide minerals. Through lead and zinc phase analysis, it is known that the distribution of galena reaches 63.78 per cent, and that of sphalerite is up to 77.16 per cent. And the oxidation rates of lead and zinc will become much more serious as the depth of exploitation increases, which is a great trouble that the mine faces with. So how to improve the recovery of mineral beneficiation is an important means to enhance the economical benefits in the mine. Many tests work have been done to develop a new bulk flotation process to enhance the Pb and Zn recovery. Flotation results of the closed circuit test indicate that the Pb and Zn recovery from the new bulk flotation process can be increase by 10 per cent and 2 per cent, respectively, which makes very considerable benefit for the mine.

The desulfurization process of lead and zinc slag is an important smelting process to obtain lead and zinc. The aim of this paper is to study the desulfurization process of high lead and zinc sulfide containing slag with oxygen blowing. The predominance area diagrams of the Pb-Zn-Fe-S-O system (Pb/(Fe+Pb+Zn)=0.176, Zn/(Fe+Pb+Zn)=0.56) at various temperature were thermodynamically constructed. The physical properties, the chemical composition and the phase transformation of the desulfurization slag were investigated. The thermodynamic results indicated that lead, zinc, and iron can be oxidized to form high lead and zinc slag. The experimental results illustrated that the sulfur content in the oxidation slag can be reduced to less than 1% as temperature increased up to 1573 K. The XRD analysis of as-quenched slag shows the PbS and ZnS phase decreased, while zincite and spinel phase (ZnxFe3-xO4+y) emerged and increased as the reaction time increased. The desulfurization process of molten slag were considered to be the first-order reaction and the apparent activation energy was estimated to be 44.46 kJ/mol. Under the experimental conditions, the mass transfer in the gas and liquid phase was likely to be the restrictive step.
