A technology has been developed for producing glass microspheres in a plasma reactor based on the wastes of enrichment of ferruginous quartzites KMA. The regularities of the influence of the flow rate of the plasma-forming argon gas and the power of the plasma reactor on the fractional composition have been established. It is shown that with an increase in the flow rate of the plasma-forming gas from 1.5 to 2.5 m3 / h and the current strength from 400 to 500 A due to the processes of coagulation, the amount of the fraction over 630 ?m increases. It has been shown that glass microspheres are enriched in aluminum and calcium oxides and depleted in silicon, magnesium, sodium, potassium, and iron oxides. It was found that under the action of high plasma temperatures, of the order of 9000 & # 150; 12,000 K, there is a complete melting and spherization of the particles with the formation of glass microspheres with a size of 80 to 1250 microns. The following operational parameters of glass microspheres based on the wastes of enrichment of ferruginous quartzites of KMA, such as microhardness, acid resistance and alkali resistance, have been investigated.
