摘要
对复杂含砷锑银矿酸性浸出渣提取银进行了研究，提出了对浸出渣进行氧化焙烧预处理再转化浸银的处理工艺，在焙烧温度６５０℃，Ｈ２ＳＯ４体系中转化，Ｎａ２ＳＯ３溶液浸出，甲醛作还原剂，银的浸出率为９４２５％，银粉品位为９４３８％。
The extraction of silver from acidic leach slime of complex arsenicbearing dyscrasite is investigated, thereby proposing the oxidizing roasting inversionleaching process. On conditions that an oxidizing roasting temperature is 650 , conversion takes place in the H2SO4 system, leaching is conducted with Na2SO4 and reduction is performed with formaldelyde, the leaching efficiency of 945% can be obtained, with a spongy silver purity of 9438%.
