Study on Optimization of Separation Effect of Selenium,Tellurium and Copper in Copper Anode Slime AITranslate
Abstract AITranslate
Based on the incomplete separation of selenium,tellurium,and copper in the selenite reduction section of the comprehensive recovery process for copper anode slime,a new process was proposed of supplementing chloride ions to the chlorinated de-selenium solution and an industrial trial of secondary selenite reduction was conducted while other parameters such as reduction time,temperature,and reductant flow rate remained unchanged.The results show that with the new process,the reduction rate of selenium in primary reduction can reach 99.72%,while the reduction degree of tellurium and copper is significantly inhi-bited.In the secondary reduction,the reduction rate of tellurium can reach 95.30%,while that of copper decreases to 4.71%.The selenium content of crude selenium product increases from 72.04%to 76.77%,the tellurium content decreases from 1.62%to 0.45%,and the copper content decreases from 2.17%to 1.01%.Compared with the original process,the improvement effect of the new process is significant.
