摘要
泥旦沟金矿采用堆浸工艺,对低品位矿石进行提金试验。试验矿石品位2.25g/t,规模4795t。金的浸出率67.74％,单位矿石利润66.8元/t,经济临界品位降至1.23g/t,矿山服务年限得到有效延长。
A gold-extracting test using heap leaching technology, was conducted in theNidangou gold mine. The ore grade for test was 2. 25g/t,heap scale amount to 4795t,leach-ing rate of gold reached 67.74%,profit of per ton ores attained 6.68 yuan,economic criticalgrade decreased to 1.23g/t,and the serving life of mine have been prolonged effectively.
