Wastes of Nickel Production in the Technology of Building Ceramics

An analysis of the needs and assessment of the potential of brick and tile raw materials for the Orenburg region in the production of ceramic bricks was carried out. The high concentration of mining and smelting enterprises in the Ural region determines the need to consider industrial waste, including nickel slag, as a possible raw material for the production of ceramic bricks. Statistical data on the quantitative stock of brick clays and formed technogenic wastes of nickel production on the territory of the Orenburg region are presented. A review of existing developments in the field of production of ceramic bricks, with the addition of nickel slag, was carried out, taking into account the advantages and disadvantages of the finished product. The properties of nickel slag obtained at metallurgical enterprises of the Orenburg region and the features of its use as a component in the composition of ceramic bricks are described. The compositions of the ceramic mass were developed using clay from the Khalilovskoye deposit (Orenburg region) with the addition of nickel slag (36, 46 and 56% by weight) and their physical and mechanical properties (ultimate compressive strength, ultimate flexural strength, frost resistance, water absorption) were determined. The presented studies show that the development of ceramic products from local raw materials using nickel production waste is a promising direction and allows the production of competitive local building materials.
