A new process of enrichment Cu in molten copper slag under electric field was put forward in this article. The experiments were carried out in the laboratory on a kilogram scale. The copper slag was improved mobility by the technique of carbon reduction. The effects of temperature, electric field strength and intermittent feeding speed were investigated on Cu migration. The results show that the best experimental conditions are the temperature at 1523K, electric field strength is 1.5V•cm-1 and feeding rates is 15 g•(10min)-1. The copper content of the slag was able to decrease below 0.6wt%. The process was compared to the traditional electric furnace process of slag cleaning, it showed that effectively reduced the energy consumption and heat loss, and reduced the harmful gas emissions such as SO2 and CO2, and improved the efficiency of the cleaning.
