Preparation of clarificant for glass from As-Sb dust

The arsenic and antimony dust arisen from the volatilization of anode slime in the electrolysis of copper and lead was used as raw materials. The process of direct volatilization or reduction oxidation volatilization was employed to produce the mixture of As 2O 3 and Sb 2O 3, and then Na 2SO 4 was added to produce clarificant for glass. The optimizing technology conditions which were obtained from the test of preparing the mixture of pure As 2O 3 and Sb 2O 3 by the volatilization method are reaction temperature 900 ℃ and reaction time about 30 min. The glass clarificant produced meets industrial application standard.
