A serious ecological issue not only in Kazakhstan, but also in the world is deposits of waste from the mining and metallurgical complex, the amount of which exceeds the production volume. The article provides information about the possibility of using waste from the mining and metallurgical complex – shungite materials (shungite ore, concentrate, and “tails” after enrichment) obtained by multi-stage flotation enrichment as a filler in the production of tile adhesives. The chemical composition of shungite materials has been studied by the method of X-ray phase elemental analysis. By the method of experimental selection based on the manufacturer of concrete additives and dry building mixes, the optimal amount of shungite material added to the resulting formulations was determined without deterioration of the physical and mechanical properties of the samples (adhesive strength, open time, sliding, distribution) relative to standard analogs. It is established that the obtained tile adhesives fully comply with the standards, are environmentally safe, the adhesive strength after twenty-eight days is 1.03 N/mm2, and allow to reduce cement consumption in the production of tile adhesives by 30%, which significantly affects the reduction of the cost of the products. Experiments with shungite concentrate (carbon content 55.4%) obtained by multistage flotation enrichment as a black pigment for grout production based on the Ceresit CE33 Graphite/ Grey trademark showed high physical and mechanical properties compared to standard samples.
