摘要:
对云南某高碳酸盐型含银氧化铜矿进行铜银同步浮选实验研究。结果表明，通过闭路实验，可获得铜银精矿Cu品位22.03%，Cu回收率71.69%， Ag品位1095 g/t，Ag回收率81.90%的技术指标。采用此同步浮选工艺可有效选别该含银氧化铜矿。
Abstract:A synchronous flotation test of copper and silver in a silver-bearing copper oxide ore with high carbonate gangue from Yunnan was studied. The results show that copper and silver concentrate copper grade of 22.03% and recovery of 71.69% was achieved through the closed circuit flotation test. And the grade and recovery of silver in copper concentrate were relatively 1095 g/t and 81.90%. The synchronous flotation technology using in the silver-bearing copper oxide ore is effectual .
