摘　　要：塔式磨浸机的细磨和边磨边浸氰化浸出工艺对吉林大线沟含金尾矿的浸出回收金实验结果表明,在90%通过200目的磨矿细度下,氰化浸出12h,金的浸出率93.3%;在同样磨矿细度下,金的边磨边浸浸出率95%。处理1 t含金尾矿生产成本为40元。A new process was presented. Experimental goldby cyanidefor leaching 12 leaching at the same grinding of fine grinding and leaching while grinding on a gold-beating tailings in a tower mill results on Daxiangou tailings in Jilin province in China showed that the dissolution of h is 93.3% under the grinding size of 90% 〈200 mesh, contrast to 95% of grindingsize. The cost of extraction for the gold-bearing tailings is 40 yuan per ton.
