中文摘要: 分析了铜阳极泥火法提取贵金属碱性渣的物相组成,提出了碱浸出、净化、电解制备高纯碲的工艺,重点讨论碱浸对碲浸出率的影响以及工艺参数对碲纯度的影响。通过试验,全流程碲收率为92.25%,高纯碲产品达到YS/T222—2010标准;含硒溶液经二氧化硫还原,可得到含量96.56%、回收率90.17%的粗硒。
Abstract:Phase composition of alkaline residue after extraction of precious metal from copper anode slime by pyrogenic process was analyzed. Process of alkaline leaching, purification and electrolytic preparation of high-purity tellurium was proposed. Influence of alkaline leaching on tellurium leaching rate and effects of technological parameters on tellurium purity were discussed. Through experiments, total tellurium recovery is 92.25%, and high-purity tellurium product meets the requirement of standard of YS/T 222—2010. After reduction of selenium solution by sulfur dioxide, crude selenium with selenium content of 96.56% and recovery of 90.17% is obtained.
