| Abstract: |
| The metal minerals of a lead-zinc ore in Yunnan Province are mainly sphalerite, Galena and pyrite, while the gangue minerals are mainly quartz, mica, chlorite and ORTHOCLASE, etc. , the optimum process parameters are obtained. Lead and zinc are flotation preferentially, and two roughing, two sweeping and three fining processes are adopted respectively, the technological indexes of lead grade 66.01% , zinc 3.40% , gold 1.87 G / T, silver 1846 G / T, lead recovery 87.71% and zinc grade 62.29% , lead 1.05% , gold 0.52 G / T, silver 160 G / T, zinc recovery 83.05% can be obtained, it provides the main reference for the exploitation of the ore resources. |
