| 摘 要： | 氨性硫代硫酸盐浸出金银过程中硫代硫酸盐消耗量大是阻碍该技术应用于工业生产中的主要因素之一。浸出体系中铜离子和铜氨络离子浓度是影响硫代硫酸盐消耗量的关键因素，通过控制铜离子和铜氨络离子的浓度、加入添加剂或预处理矿石均可达到降低硫代硫酸盐消耗的目的。

| Abstract: | The large consumption of thiosulfate in the process of leaching gold and silver by ammonia thiosulfate is one of important factors that hinders the application of this technology in industry. In the leaching system, the concentration of copper ions and copper ammine complex ions are the key factors that affect the consumption of thiosulfate. The purpose of reducing thiosulfate consumption can be achieved by regulating the concentration of copper ions and copper ammine ions, adding additives, and pre-treating ore. |
