Possibility of Using Enrichment Tailings of KMA Ferruginous Quartzite in the Production of Ceramic Building Materials.

The possibility of using the enrichment tailings of KMA ferruginous quartzites is considered. The chemical composition of waste from Lebedinsky MPP was investigated. It was established that the main components of the waste are quartz, magnetite, as well as dolomite, calcium, and magnesium carbonates. It is shown that the chemical composition and particle size distribution of waste are characterized by stability, which allows it to be used as a corrective additive to ceramic mixtures in the production of wall ceramics.
