Abstract

Based on estimated distribution ratios of several impurity elements between Na2CO3 slag and molten copper, a mathematical model has been developed to discuss the application of Na2CO3 flux to the removal of impurities from molten copper, in terms of the Na2CO3 flux consumption. The effectiveness of the Na2CO3 flux treatment to reduce the impurity contents in molten copper to 0.1 mass ppm, the level required for the high purity copper, is discussed by the model and confirmed by equilibrium distribution experiments.
