摘要
铅阳极泥作为回收银的重要原料,在含有较高品位银量的同时,还含有铋等有价金属,在贵铅熔炼时,90%以上的铋留在贵铅中,而在氧化过程80%以上的铋汇集在氧化渣中,成为回收生产金属铋的重要原料,利用还原熔炼方法,对氧化渣中铋进行了回收,创造了一定经济效益。
Lead Anode slime to be taken as the most important raw materials for recoverying the silver, with the higher grade silver quantity contained, it also contained some valuble metals such as bismuth. When smelting the wet lead, more than 90% bismuth will be kept in the wet lead. but in the process of oxidizing, more than 80% bismuth will be gathered in the oxidizing residues, and it will become the most important raw materials for recoverying and producing the metal bismuth. By using the reducing smelting process, the bismuth will be recovered in the oxidizing residues, and created certain economic profits.
