【摘要】 铅阳极泥酸浸富银渣中的银呈氯化银状态。这种状态在下步火法熔炼时会造成损失， 因此应首先转化为单质银。作者用置换法或碱处理法使氯化银转化为单质银， 转化率９５．４ ％ ～９９．６９ ％ ， 银回收率＞ ９９．９ ％ 。更多还原

【Abstract】 The state of silver in silver-rich residue from leaching of lead anodic slime with acid is AgCl. In order to avoid loss of silver in the subsequent smelting stage,the state of AgCl should be changed to elemental silver.The processes of replacement or treatment by soda were indroduced in the present paper.About 95 4%～99 69% of AgCl was reduced to elemental silver and more than 99 9% of silver was recovered.更多还原
