| Abstract: |
| A new generation of green purification technology for copper electrolyte has realized purification of copper electrolyte with directional separation of impurity arsenic, antimony and bismuth, and solved the problems of generation of poisonous and harmful gas i.e., hydrogen arsenide and acid mist, and repeated smelting of materials during purification process. Arsenic was effectively open circuit, harmful gas is no longer produced, and clean and green production has been achieved. The original purification process of electrolyte of electric copper removal by induced purification is substituted to produce cathode copper. All copper extracted from enrichment process can be directly produce A-grade cathode copper products, and power consumption reduces by 55%. Transformation from traditional smelting to green and clean smelting is realized. |
