摘　　要：研究煅烧预处理温度对嗜酸氧化亚铁硫杆菌浸出废旧手机板中多种有色金属的影响。结果表明,预处理温度越高,零价金属的浸出效率相对越高。生物浸出15天后,铜、镍和锌的浸出率分别达到95.14%、96.53%和98.45%,锡先溶解而后以沉淀形式存在于浸出残渣中。低温煅烧预处理不仅缩短了浸出周期,还提高了部分有色金属的浸出率。The effects of low temperature calcination pretreatment on bioleaching of non-ferrous metals from waste mobile phone scraps with Acidithiobacillus ferrooxidans（hereinafter referred to as T.f）were investigated.The results show that after 15 days of bioleaching,the leaching rate of copper,nickel and zinc is 95.14%,96.53% and 98.45% respectively,and tin first dissolves in early days and then precipitates in leaching residues.Low temperature calcination pretreatment not only shortens leaching period,but also improves leaching rate of some non-ferrous metals.
