摘　　要：为了提高云南某铜银硫化矿银回收率,通过试验研究对2000 t/d选矿厂的工艺流程进行了优化。试验结果表明,在原磨浮工艺流程上,采用石灰加KJ14作组合抑制剂来提高银回收率,新的药剂制度对该矿石具有良好的适应性。In order to improve the silver recovery of a silver copper sulphide ore from Yunnan, the processing flowsheet of a 2000 t/d concentrator was optimized by bench-scale test. The test results showed that with the exist- ing primary grinding and flotation process, the recovery of silver , can be improved by using lime and KJ14 as combined regulator. The new reagent regime has a good adaptability to the ore.
