摘　　要：西藏某选矿厂,浮选流程为1粗3精3扫,处理原矿铜品位为0.85%,铜氧化率为6.14%的硫化铜矿石,最终得到铜回收率为88.79%,精矿铜品位为19.91%的选矿指标。为了进一步提升铜回收率指标,针对该选矿厂浮选流程结构,通过现场考查和小型实验进行优化,研究表明,相同的药剂制度,将浮选流程结构调整为“部分快速浮选+两次粗选”,在得到合格铜精矿的同时,铜回收率达到了92.18%,铜回收率提高了3.39个百分点。选矿厂根据实验结论进行浮选流程结构优化改造,铜回收率提高了2.93个百分点,达到了91.72%。结论对同类别选矿厂生产具有重要的参考和借鉴意义。In a concentrator in Xizang,the flotation flowsheet is one roughing three cleaning three scavenging,the copper grade of the raw ore is 0.85%and the copper oxidation rate is 6.14%.The copper recovery rate is about 88.79%,and the copper grade of the concentrate is 19.91%.In order to improve the recovery of copper,the flotation process structure of the concentrator was optimized by field investigation and small scale test,by adjusting the structure of flotation process to“partial rapid flotation+two roughing”,the recovery of copper was 92.18%and 3.39%higher than before.According to the test results,the flotation flowsheet was optimized and the recovery of copper was increased by 2.93 percentage points to 91.72%.The conclusion has important reference significance for the production of the same type of concentrators.
