How to increase the ration of iron and heat recovery from the smelting steel slag is an important issue in metallurgy. So a study of extracting iron from converter slag was done by smelting reduction method. Here we studied the effect of CaO/SiO2 on the recovery during smelting reduction. Results showed that the CaO/SiO2 directly regulated the reduction reaction of Fe2+ / Fe3+, the viscosity of slag...
