津巴布韦已开采过四千个金矿,目前约有350个正处于生产之中.其中很多个根本不是金矿而是堆浸处理厂,它是从早期选金的尾矿堆中回收残余的金.这个国家大多数尾矿堆由硅质成分组成,产自于绿岩母岩的石英矿脉中.因为这种矿堆对氰化物溶液的渗透性不好,因此,不适合采用最便宜的尾矿堆处理法—堆浸.虽然在津巴布韦的某些地方采用了堆浸,如Camper down矿山就是成功的例子.这是因为所处理的物料含有褐铁矿,使被浸出的75毫米物料具有足够的渗透性.
About 4,000 gold mines have been mined in Zimbabwe, with about 350 currently in production, many of which are not gold at all but heap leaching plants that recover residual gold from tailings mines of earlier gold options Most of the tailings heaps in the country are siliceous and originate from the quartz veins of greenstone rock, which is not suitable for the cheapest tail because of its poor permeability to cyanide solutions Mining heap treatment - heap leaching Although heap leaching is used in some parts of Zimbabwe, the Camper down mine is a successful example because the material being treated contains limonite to make the leached 75 mm material sufficient Permeability.
