本文概述了堆浸的矿石试验、准备工序及堆浸工艺,作者依据本人经验和已发表的文献对其现行工艺进行综合评述.适合堆浸法的条件是矿石必须具有下列特点:(1)金的粒度必须很小;(2)金银组分必须和氰化物发生反应,或者矿石具有天然孔隙或者经破碎使金银矿物暴露在氰化物中;(3)矿石必须是不含“损害氰化物的物质”特别是Sb、Zn、Fe、Cu和As的氧化硫化物以及抑制金银在氰化物中溶解能力的其他干扰物;(4)矿石必须不含碳质成份,因为碳质成分能吸附金、银氰化物,引起有用组分过早沉淀;(5)矿石必须少含导致大量石灰消耗的酸性组分;(6)矿石必须不含过多的细粒和粘土,它们将妨碍溶液渗透,如果 This paper summarizes the heap leaching ore test, preparation process and heap leaching process, the author based on my experience and published literature on the current process of a comprehensive review of heap leaching method suitable for the conditions that the ore must have the following characteristics: (1) gold Must have a small particle size; (2) the gold and silver components must react with the cyanide or the ore has natural pores or is broken to expose the gold and silver minerals to the cyanide; (3) the ore must be free from "cyanide- Sulfur oxides of Sb, Zn, Fe, Cu and As, and other disruptors that inhibit the ability of gold and silver to dissolve in cyanide; (4) the ore must be free from carbonaceous components because the carbonaceous components can adsorb Gold, silver cyanide, causing premature precipitation of useful components; (5) the ore must contain less acidic components resulting in significant lime consumption; (6) the ore must be free of excessive fines and clays that will prevent solution penetration ,in case
