破碎硬岩在渗滤状态下的浸出实践表明,随着时间的推移,产出溶液中的有用组分浓度降低。这就会导致加工期延长和组分损耗,因为在组分的重量百分率减少到最低容许值时,浸出过程终止。此时矿石中仍保留30～50%的金属。为提高浸出过程的效率,必须按计划提高过滤速度并更新浸出液运动的途径。这就要反复疏松矿岩。改变被浸出矿岩体和浸出药剂流的结构即可在任一浸出段实现这种疏松。1989年瓦西里考夫采选公司(哈萨克斯
The leaching practice of crushed hard rock under leachate shows that the concentration of useful components in the produced solution decreases with time. This leads to extended processing times and component losses because the leaching process is terminated when the weight percentage of the components is reduced to the minimum allowable value. At this time the ore is still retained 30 to 50% of the metal. In order to increase the efficiency of the leaching process, the filtration speed must be increased and the leachate movement updated as planned. This will be repeated loose ore. This loosening can be achieved at either leaching section by changing the structure of the leached ore body and leaching of the chemical stream. 1989 Vasily Koop mining company (Kazakhstan
