金银矿石堆浸的主要优点在于可省去传统选厂所惯有的细磨、搅拌浸出,固液分离、富液净化及尾矿浆排放等高费用的工序,其主要缺点是回收率低、冶金效率不高且不易控制。柱浸试验表明在理想条件下金银回收率可达60～80％。回收率低的原因是,一些矿山急于投产,往往对矿石只略予粗碎和仅投入最低限度的设备、资金和时间,而未努力进一步提高回收率。很多矿山堆浸回收率低属于物理性质,例如堆浸表面积水、堆内出现沟流,板结
The main advantage of heap leaching of gold and silver ore is that it can eliminate the high cost processes such as fine grinding, stirring leaching, solid-liquid separation, rich liquid purification and tailings slurry discharge, which are traditionally used by traditional processing plants. The main disadvantage is that the recovery rate is low, Metallurgical efficiency is not high and not easy to control. The column immersion test shows that under the ideal conditions, the recovery rate of gold and silver can reach 60-80%. The reason for the low recovery rate is that some mines are eager to start production, often only slightly coarse ore and little equipment, capital and time are invested in, and no efforts are made to further increase the recovery rate. Many mine heap leaching recovery is low physical properties, such as heap surface water heap, pile heap flow, knot
