从尾矿坝中回收金的生物预处理Ｅ．Ｎ．Ｌａｗｓｏｎ等前言金矿山的尾矿堆或尾矿坝是由细粒矿石堆积起来的，大部分尾矿的粒度小于１５０ｕｍ。尾矿堆非常致密。水的渗透速率十分缓慢。但空气扩散是可能的。堆表物料呈碱性。堆表以下物料的性质基本不变。随着尾矿堆放时间... Biological pretreatment of gold recovered from the tailings dam. N. Lawson et al. Preface The tailings dumps or tailings dams in the gold mines are piled up by fine-grained ores, most of which have a particle size of less than 150 μm. Tailings pile is very dense. Water infiltration rate is very slow. But air diffusion is possible. Heap table material is alkaline. The properties of the following materials in the heap table are basically the same. With tailings stacking time ...
