Used refractory materials can be classified as slightly modified industrial waste, high-quality man-made raw materials that are very promising for recycling and recycling. Refractory scrap is not a toxic substance and is not accumulated in large volumes. However, its recycling is of great economic interest, since energy consumption in the primary production of refractory products (drying, firing) is a significant part of the cost of the final product. The processing of refractory scrap in order to obtain enriched powders to replace natural raw materials in the production of refractories and obtain functional materials will reduce the need for scarce refractory raw materials by more than 25% and increase the country's resource security. The development of refractory recycling technologies should begin with the study of crushing and mechanical enrichment processes. The establishment of patterns of destruction of refractory scrap in the crushing and grinding processes will make it possible to implement technologies of selective disintegration and dry enrichment based on them. According to the authors, dry processing of refractory scrap is the most promising, since it allows to increase the technospheric safety of its processing processes and reduce the cost of the entire technological chain. The paper presents the results of processing corundum-carbide scrap of silicon carbon refractories (LCCC) according to a technological scheme that includes crushing and selective crushing in devices that implement the principle of free impact. A decrease in the mass fraction of iron in the finished product was achieved from 2.7 to 1.34%. The yield of the finished product was 51.0–76.4% with a mass fraction of Al2O3 of 59.0–63.7%.
