The use of technogenous waste from the Kadamjai antimony plant as a raw material for the production of portland cement

The article investigates the temperature regime and the amount of heat required for sintering a mixture obtained from industrial waste (dump slag, flotation tailings) with the addition of natural clay. The chemical composition of industrial waste (slag, dump, flotation tailings) and natural clay, which are suitable for use as raw material for the production of Portland cement and other building materials, have been investigated. Utilization of man-made waste (Kadamzhai antimony plant) will help improve the environmental situation in the region, and on the other, reduce material costs of production to obtain new products.
