从铂钯精矿中氯化浸出Au、Pt、Pd

摘要

Gold, platinum, palladium and other precious metals were leached out as chlorine complexes by chloridizing leaching with NaClO3 as oxidizer from platinum and palladium concentrate. The optimization condition of the leaching technology was investigated in detail. The results show that the leaching rate of gold, platinum and palladium is over 99%.%针时铜阳极泥处理过程中生产的铂钯精矿,以氯酸钠为氧化剂,采用湿法氯化浸出,使金、铂、钯等贵金属以氯配合物进入溶液.研究了浸出的最佳工艺条件.结果表明,金、铂、钯的浸出率均达到99％以上.
