加入助浸剂提取难浸银精粉中银的研究

Study on Silver Extraction from Refractory Silver Concentrate with the Adding of Leaching Agents

对于含杂质比较多的难浸银精粉 ,采用助浸剂浸出 ,银浸出率可由常规方法的 6 0 %提高到 85 %以上 ,浸出周期由常规的 4 8～ 72h缩短至 2 4～ 36h。

The silver leaching rate can be raised from conventional 60% up to >85% with the adding of leaching agents for the refractory silver concentrate with high impurity contents, the leaching time can be reduced from 48～72h to 24～36h.
