矿石直接堆浸提取金属的方法已有很长的历史:以前此法主要用于处理某些铜矿和铀矿等。本世纪六十年代后期由于金、银价格大幅度上涨,使原来认为没有开采价值的低品金,银矿以及从前遗弃的一些低品位含金、银废矿和废料变成具有回收价值的宝贵原料。为了从这些原料中提取金、银、采用堆浸法是较为理想的方法。同时,由于采用活性炭从含金量较低的氰化物溶液中吸附金的技术臻于完善, The direct heap leaching of ore extraction method has a long history of metal: This method is mainly used for the treatment of some copper and uranium ore. In the late 1960s, due to the sharp rise in the gold and silver prices, low-grade gold and silver mines originally thought of as undeclared and some of the low-grade gold, silver waste and scrap materials abandoned in the past were turned into precious reclaimed value raw material. In order to extract gold, silver from these raw materials, heap leaching method is the ideal method. At the same time, as the technology of using activated carbon to adsorb gold from the cyanide solution with lower gold content has been improved,
