摘要: 针对经典的电解法精炼黄金的一些不足, 提出了湿法化学方法提纯, 并对金山金矿黄金精炼提纯进行了试验研究。通过批量试验结果表明, 采用该方法提纯, 金的纯度可达99.99%、金的回收率高达99.99%, 而且工艺流程简单、操作技术条件易掌握、污染少、生产周期短、黄金积压少。Abstract: Focus on some shortcomings exist in the electrorefining of gold, the paper present a new hydrometallurgy in refining gold.An experimental study of refining gold is made, the experimental results show that the recovery of gold come up to 99.99%, the purity of gold come up to 99.99%.The characteristics of technology include: the technological process is simple; the operating condition of technology is easily mastered; having less pollution; the cycle of production is very short and the deposition of gold is less.
