| 摘 要： | 采用柱浸法对紫金山矿区含铜金矿进行浸出试验,分别考察矿样粒度、铜品位、喷淋强度、氰化钠喷淋浓度和浸出时间对浸出率的影响。结果表明,采用堆浸法处理该含铜金矿矿样是可行的,对-80mm粒级在15天内金浸出率大于86%,浸出前期金、铜同时浸出,在浸出后期出现沉铜现象。

| Abstract: | Copper-bearing gold ore in Zijinshan was column leached. The effects of particle size and copper grade of ore, spraying intensity, spraying concentration of sodium cyanide and leaching time on leaching rate were investigated. The results show that it is feasible to recover gold from this gold ore by dump leaching. The leaching rate of gold within 15 days is 86% above for -80 mm size fraction. Gold and copper are leached simultaneously at early stage, and copper is deposited at following stage. |
