Recovery of Silver and Lead through Reprocessing of Lead Tailings from Yunnan

Abstract:

Properties of the ore were studied by chemical analysis and Lead phase. Research shows that the lead tailings contains 15.47 g/t of silver and 0.62% of lead, lead minerals are mainly Galena, Anglesite and Finnemanite, Silver minerals and galena symbiosis, besides, gangue minerals are mainly quartz. Based on properties of the tailings, flotation feasibility pilot study was conducted. Results show that excellent test indexes that a Ag grade of 137.09 g/t with a Ag recovery of 55.27% and a Pb grade of 5.85% with a Pb recovery of 60.35% were obtained under the used process and reagent system conditions.
