Abstract
In order to maximize the use of copper slag, a new idea that copper slag is reduced to smelt copper-containing antimicrobial stainless steel was proposed. But copper-iron reduced from copper slag contains a large number of copper matte, making sulfur content high. In this article, desulfurization of copper-iron was studied. The Fact-Sage software was used to calculate ΔG of the desulfurization reaction. Calcium oxide, calcium carbide and ferromanganese were used as desulfurization agent. The results show that desulfurization capacity of calcium oxide is poor, but with addition of carbon, desulfurization effect of calcium oxide will be enhanced. Calcium carbide and ferromanganese have good desulfurization effect.
