Exploring the possibility of producing building ceramic from mining wastes
The results of analysis ceramic mixtures and burnt samples of apatite-nepheline, copper-nickel and iron ore dressing wastes, demonstrating their possible uses in the production of building ceramic, are presented. Compositions for ceramic with low heat conductivity and improved physical-mechanical characteristics are proposed. The possibility of enhancing the frost resistance of the ceramic materials has been substantiated, which includes controlling of the charge component (ferruginous quartzite benefication wastes) grain size, as well as increasing of the ceramic surface density.
