Using a New Bulk Flotation Process to Enhance the Recovery of Mineral Beneficiation in a Lead-Zinc Sulfide-Oxide Mixed Ore

Abstract:

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.
