针对某难浸氧化金矿石的矿石性质,采用硝酸预浸技术进行提金试验研究. 其结果表明:在最佳试验条件下,可获得金浸出率87 . 86 %、银浸出率76 . 56 %的较好指标. 相对于其他处理工艺,硝酸预浸技术可以显著提高金、银的浸出率,并降低氰化物的消耗量,减轻生产成本压力,达到了资源最大化利用和综合回收的目的.
In light of the hard-to-leach property of one oxide gold ore,experimental research is conducted using nitration pre-leaching technique. The results show that under optimal conditions,gold leaching rate can reach 87. 86%and silver leaching rate 76. 56 %. Compared to other treatment techniques,nitration pre-leaching technique signifi-cantly increases gold and silver leaching rate and reduces the consumption of cyanide,cutting production cost and a-chieving the goal of full utilization of resources and comprehensive recovery.
