针对铁山垅钨矿-0.019mm细粒尾矿中WO3含量达0.19%、回收困难的难题,杨坑山选厂在“浓缩-浮选-重选”联合工艺中试验采用悬振选矿机回收摇床尾矿中的微细粒黑钨矿。通过近2年的实验室试验和现场工业试验,一次选别可获得品位为3.28%的钨精矿,钨回收率为43.85%,富集比达19,有效解决了细粒级黑钨矿回收困难的难题,取得了良好的选矿效果。 In view of the difficult problem of WO3 content of 0.19% fine-grained tailings from Tieshan tungsten mine, which is difficult to be recycled, the test of Yangkengshan Concentrator in “Concentration-Flotation-Reselection” Recycling shaker tailings in the fine-grained wolframite. Through nearly two years of laboratory tests and field industrial tests, the grade of tungsten concentrate with the grade of 3.28% can be obtained by one sorting, the recovery rate of tungsten is 43.85% and the enrichment ratio is up to 19, which effectively solves the recovery of fine-grained wolframite Difficult problems, and achieved good dressing results.
