The use of mining and metallurgical waste for the production of building supplies reduces the burden on the environment and serves the sustainable development of the region’s industry at the same time. Russia has substantiated the possibility of producing ceramic construction materials of compression molding from a unique mixture of substances based on waste slag of copper–nickel productions, tailings of enrichment of apatite–nepheline ores, and ferruginous quartzites of enterprises of the Murmansk region. The effect of forming pressure (20, 50, and 100 MPa) on the properties of ceramic materials was studied. It is shown that an increase in molding pressure leads to an increase in the physical and mechanical properties of ceramic materials and to a decrease in fire shrinkage and water absorption. The use of a forming pressure of 100 MPa and a firing temperature of 1050 °C makes it possible to obtain a wall clinker brick; at a firing temperature of 1100 °C and a forming pressure of 20–100 MPa, a road clinker brick can be produced. Ceramic samples with frost resistance of more than 200 cycles were received. View Full-Text
