摘要
采用二次酸洗脱铜、亚硫酸钠还原碲、中和沉淀铋的方法对铜、碲、铋等含量较高的中和渣进行了综合利用的新技术研究,形成了一整套的工业化的回收技术。碲、铜、铋的回收率可分别达到92.8%,95.5%,97.2%,该工艺设备简单,易操作,适应性较强,经济效益显著。。
New technology research on comprehensive utilization of neutralized slag with high Cu,Bi and Te was carried out by using secondary acid pickling for copper removal,sodium sulfite for tellurium reduction and neutralization for bismuth sedimentation,which brings the completely industrialized recovery technology coming into being.The recovery of tellurium,copper and bismuth can be up to 92.8%,95.5% and 97.2% respectively.This new technology can be easily operated and brings remarkable economic benefits with simple equipments.
