Waste of dressing of nonferrous metal ores in ceramic production

The possibility of using copper-nickel ore dressing wastes as a component of ceramic masses for the production of ceramic tiles has been investigated. The optimal content of waste in ceramic masses and firing conditions have been determined. The physical and mechanical characteristics of the materials obtained have been studied. It has been established that the wastes of the concentration of copper-nickel ores can be used in the compositions of ceramic masses to obtain facing tiles with satisfactory properties: water absorption - 12.7 - 13.3%, bending strength - 10.0 - 12.9 MPa, frost resistance - more than 25 cycles.
