Abstract: Silicon dioxide containing waste flue dust from the producton of silicon metal and silicon alloys is converted to crystalline zeolite molecular sieves of Type Y by (1) dissolving the flue dust in alkali metal hydroxide solution with the formation of alkali metal silicate solution having the module (SiO2:MeI2O) in the range of 4.0:1 to 5.0:1 at a temperature of 60 DEG -110 DEG C.; (2) purifying the thus obtained alkali metal silicate solution from organic constituents by treatment with activated carbon and/or an oxidizing agent and separating the non-decomposable residue from the solution; and (3) reacting alkali metal aluminate solution present at room temperature with the diluted, purified alkali metal silicate solution with a module (SiO2:MeI2O) of 4.0:1 to 5.0:1 obtained by steps (1) and (2) and subsequently crystallizing the reaction mixture (SiO2:Al2O3=4-7:1, MeI2O:SiO2=0.4-0.7, H2O:MeI2O=30-50:1) at a temperature of 75 DEG -100 DEG C. with stirring for a period of 8-48 hours, subsequently filtering to remove the product from the mother liquor, washing and drying to recover a zeolite molecular sieve of Type Y with a Faujasite structure having a degree of whiteness according to Berger (A. Berger, Die Farbe, 8 Nr. 4/6 (1959) 187-202) at 460 mu in the range of 90-95%.
