Ore samples, collected from a lead-zinc oxide ore deposit in Sichuan province, China, are very difficult to treat with such characteristics as low grade, uneven mineral particle distribution and high containing of slime. It is very difficult to separate the lead minerals and zinc minerals, especially for the recovery of zinc oxide minerals. On the basis of flotation characteristics study to gangue and useful minerals, author studied flotation behavior of lead-zinc oxide ore with new collectors (KM21 and YO-1), and carried out the experiment on separating useful minerals from gangue minerals. Test results showed, a lead concentrate with a grade of 59.78 percent and a recovery of 86.49 percent and a zinc concentrate with a grade of 48.53 percent and a recovery of 84.92 percent were obtained from the crude ore with the oxidation rate of 74.34 percent and 89.30 percent of lead and zinc respectively, which realized the high efficient flotation separation of the refractory lead-zinc oxide ores.

A bench-scale beneficiation study was performed on low-grade complex lead-zinc ore of Duddar area, District Lasbela, Balochistan Province, Pakistan. The polymetallic ore under investigation contains galena and sphalerite as valuable minerals of lead and zinc. The low-grade ore was upgraded by selective sequential froth flotation technology to recover both minerals. An effort was made to investigate the effect of important variables on grade and recovery of concentrates and to design the process flow sheet. Different parameters of flotation process such as particle size of the feed, pH and % solids of the pulp, speed of impeller, type of reagents (collectors, frothers, regulators and modifiers) and their quantities, conditioning time and flotation time were optimized to attain maximum grade and recovery of respective concentrates. The rougher concentrates obtained were subjected to one regrinding and two cleaning operations to achieve higher-grade concentrates of both metals. Bench-scale flotation tests show that it is possible to obtain a lead concentrate assaying 65.24% Pb with recovery rate of 81.32% and a zinc concentrate containing 55.63% Zn content with recovery rate of 80.28%. Both the concentrates meet the specifications required for metallurgical and chemical grades.
