摘要
为解决高泥质金矿石金浸出率低的问题,对某铁帽型金矿石开展了制粒堆浸提金的现场试验研究。试验结果表明,对于这类含泥较多的铁帽型金矿石,采用制粒堆浸工艺,可以获得较好的技术指标。金的浸出率由常规浸出法的33%提高到72%。
To increase leaching rate of gold in high-clay gold ore, the ore is formed grains, then is heaped leachingwith cyanide solution.The experiment results indicate that the method is useful for the high-clay gold ore and leaching rate of gold can reach to 72%.
