摘　　要：乌拉嘎金矿浮选精矿的氰化尾矿 ,采用旋流器脱泥富集、沉砂和溢流用压滤机压滤、滤饼焙烧制酸、烧渣氰化浸金工艺处理 ,使浮选厂金总回收率提高 5 .3% ,并且年可产硫酸 1.8万t。该工艺不但充分利用了矿产资源 ,而且可获得显著的经济效益。To treat cyanide tailing of flotation gold concentrate in Wulaga gold mine by cyclone concentration and mud-removal,then the sand and overflow are filtered by pressure filter and the filter cake are roasted to make acid,again the calcined ores are treated by cyanide leaching of gold.By this way,the total gold recovery rate improves by 5.3% besides annual output of 18 thousand tons of sulphuric acid.This technology not only fully makes use of mineral resources,but also obtains considerably economic benefit.
