Abstract

The chemical-analytical and physico-chemical properties of flotation waste generated during the enrichment of lead-zinc ores of the Almalyk MMC, steelmaking slags of Uzmetkombinat JSC, formed after the extraction of residual ferrous compounds and limestones of the Shavazsay deposit for the purpose of polishing Portland cement clinker on their basis, have been studied. As a result of experiments, a real possibility was established of obtaining Portland cement clinker of optimal mineralogical composition based on the studied waste, used as the main component in raw mixtures, under optimal firing temperature conditions.
