摘要
通过对甘肃省某复杂难处理银多金属氧化矿的选矿试验研究,确定了适宜该矿的选矿工艺流程为优先浮选。该矿采用D-421捕收剂、Z-205高效复合起泡剂优先浮选金银精矿;而后采用硫化钠、D-421和Z-205浮选得到铅精矿。本次试验大幅度提高了金、银回收率。生产实践结果表明工艺条件合理,指标稳定可靠。
Based on flotation research on a complex hard-processing oxide polymetallic silver ore in Gansu,the optimal flotation process is suitable for this ores.In process,gold and silver concentrate are optimally obtained with high effective mixed collector D-421 and high effective mixed frother Z-205,then lead concentrate is achieved by flotation with regulator Na2S,D-421 and Z-205.The recovery of Au and Ag can be greatly improved in the test.The production practice indicates that the technology conditions are reasonable with stable production indexes.
