摘要
对小秦岭地区难选氧化金矿石进行了选冶试验研究,用浮选法将低品位矿石富集成高品位的精矿,精矿用炭浸法回收,原矿金1.82 g/t,浮选金回收率80.52%,炭浆提金回收率97.53%,金总回收率78.53%。既降低了矿石入选品位,又提高了经济效益。
The experimental research on beneficiation-metallurgy process of refractory oxidized gold ores in Xiaoqinlin area was carried on.Low-grade gold ores were enriched by flotation process,and flotation concentrate was recovered with carbon-in-leach process.Under the condition of the run-of-mine ore of gold 1.82 g/t,the total recovery of gold 78.52% was obtained,with a recovery of gold 80.52% by flotation process and 97.53% by carbon-in-leach process.The process not only reduced the grade of run-of-mine ore,but also improved economic efficiency.
