我矿铅锌浮选尾矿富含黄铁矿。原采用在尾矿库自然沉积,从尾矿矿浆流源头的黄铁矿富集带中用人工挖掘部分黄铁矿作为硫精矿出售,硫精矿质量低且不稳定,黄铁矿损失大。为了保证硫精矿质量,提高硫回收率和企业经济效益,在广州有色金属研究院的协助下,我矿新建一座用螺旋溜槽—旋流器从铅锌浮选尾矿中回收黄铁矿的重选车间。通过试生产及半年以来的生
Mine lead-zinc flotation tailings are rich in pyrite. Originally used in the natural deposition of the tailings ponds, some pyrite was excavated from the pyrite enrichment zone at the source of the tailings pulp stream for sale as a sulfur concentrate with low and unstable sulfur concentrate and large pyrite loss . In order to ensure the quality of sulfur concentrate and increase sulfur recovery rate and economic benefits of enterprises, with the help of Guangzhou Nonferrous Metal Research Institute, I set up a new mine to recover pyrite from the lead-zinc flotation tailings with spiral chute - cyclone Re-election workshop. Passed the trial production and six months since the students
