堆浸设计的先决条伴是矿石的组成、储量和品位.由于小型或低品位金矿用常规的氰化法处理不经济,但适于堆浸.在进行工业生产之前,要先进行可行性研究,以确定矿石是否适合堆浸,如:堆浸的矿石必须具有足够的渗透性,含有害氰化的杂质少,细粒金表面干净,含泥量少等.在此基础上再进行实验室和中间试验厂试验,从中确定矿石需要的饱和溶液量,破碎粒度与堆浸时间之比,合适的氰化物浓度和消耗量,碱的选择、浓度和消耗量,溶液喷淋方式,排泄时间,洗涤次数与时间以及溶液中的含氧量 The prerequisites for heap leaching are the composition, reserves and grade of the ore, as small or low grade gold mines are not economically viable for conventional cyanidation but are suitable for heap leaching. Feasibility studies prior to industrial production Study to determine whether the ore is suitable for heap leaching, such as: heap impregnated ore must have sufficient permeability, with less harmful cyanide impurities, fine gold surface clean, less mud content, etc. Based on this experiment Room and pilot plant trials to determine the amount of saturated solution required for the ore, the ratio of crushed particle size to heap leach time, the appropriate cyanide concentration and consumption, the choice of base, concentration and consumption, solution spray pattern, excretion time , Washing times and times, and oxygen content in solution
