| Abstract: |
| The pretreatment technology for removal of high-content impurity elements in copper anode slime in acidic medium is studied.The results show that the notable metals such as gold and silver can be enriched and the impurity elements including copper,stibium,bismuth and others can be efficiently removed at a certain acidity and chlorion concentration,with corresponding elimination rates of 46.5%,65% and 85%.The rate for pre-treating slag is 55%.The optimized processing scheme has been put forward and into practice with a good result. |
