The Wujiaoshan pyrite in Xuyong, southern Sichuan contains S18.86%, containing 16.64% Fe, and the harmful components Pb, Zn, As and F are all less than 0.05%. Main mineral ores - pyrite ore most coarse dissemination size, there are few fine dissemination size. According to the ore properties and comparative test results of the Chengdu Institute of Geological Survey of China, the heavy (jigging)-floating combined process selection process was carried out on the basis of laboratory tests, and the test results obtained were re-elected. The recovery rate of jigging operations was 93.52%, and the recovery rate of flotation operations was 95.29%. After being treated with mine water and lime, it is used for flotation. The final sulfur grade of the heavy-floating process is 50.19%, the recovery rate is 89.68%, the Fe grade is 43.37%, and the recovery rate is 87.31%. The product inspection of the flotation concentrate shows that the pyrite content in the sulfur concentrate reaches 94.66%, which meets the standard of high-quality first-grade sulfur concentrate. At the same time, the coarse tailings produced by it can be directly discharged into the tailings pond, effectively utilizing the sulfur and iron in the pyrite, so that the first mine becomes a second mine, greatly improving the resource value of the southern Sichuan pyrite mine. The economic benefits are very significant. In addition, the research technology can not only effectively control the tailings, but also treat the harmful mine water into recycled production water. The ore dressing tail water can meet the water quality standard of farmland irrigation water. The application of this research is not only an industrial demonstration of the development and utilization of Wujiaoshan pyrite, but also has a general guiding significance for the comprehensive development and rational utilization of the southern Sichuan pyrite mine. It will provide important for the construction of Zhangzhou into a chemical industrial city. Raw material guarantee.
