Abstract:The properties of Mulliashi copper oxide ore in Zambia are complex, which is treated by sulfuric acid leaching-extraction-electrodeposition process. In order to reduce the influence of impurities on electrodeposition operations and effectively improve the quality of cathode copper products, technological innovation research and application have been carried out in multiple operating systems such as leaching, extraction and electrodeposition, including branch acid addition in stirred leaching, multi-stage purification of leaching solution, efficient extraction, and impurity removal by loaded organic phase purification. Results indicates that through a variety of technical innovation and transformation, the Mulliashi hydrometallurgical plant reduces the content of harmful ions and flocculants from the production source and process. This has minimized the influence of impurities on electrodeposition operations, achieving an increase in current efficiency to over 96%, raising the average purity of cathode copper products to 99.9988%, with more than 50% of cathode copper purity exceeding 99.9990%. These advancements have effectively achieved the goal of enhancing the quality and efficiency of the enterprise.
