【Abstract】 Although the melting points of slag bearing high tungsten and silicon formed in the tin smelting process are different,the viscosity is very high,which develops the capability of frothing.It is impossible to conduct the slag fuming only by a single fuming furnace.In this study,the major phases of slag are determined,the smelting properties of slag,the effect of various compositions and the major reactions inside the furnace are investigated as well.Good results are achieved by treating the slag at a right slag to ore mixture ratio.A 4 M 2 fuming furnace has been set up in a smelter in Gang Nan to treat the similar frothy slag bearing high tungsten and silicon,which has fulfilled the commercial production.更多还原
