摘要
研究了用亚硫酸钠用分银渣中浸出银。分银渣经过焙烧将难浸出的银转化成易浸出的银,加入FeCl3酸性水溶液预处理,再用亚硫酸钠浸出银,银的浸出率可达95%以上。
Leaching of Ag from residue containing silver with sodium sulfite are studied. Residue containing silver firstly is roasted at 400℃ and pretreated with acidic FeCl3 solution, then leached Ag with sodium sulfite, leaching rate of Ag is above 95% .
