摘要：
Mixtures in the system Na2SO4 + C + SiO2 after heat-treatment at different temperatures are investigated. A characteristic feature of the interaction at 900A degrees C is flotation of quartz grains together with the formation of a dense silica-containing surface layer. Separation of the mixture with flotation of incompletely fused material is characteristic for commercial technology with reducer deficiency. The reactivity of sulfates and carbons is observed to depend explicitly on their dispersity. A combination of coarse sulfate and finely dispersed carbon is best.
