State-of-the-art formation of red mud during industrial processing of bauxite in the Sverdlovsk region (Russian Federation) is presented. Red mud chemical composition is presented, and an analysis of existing ways in which they are utilised is executed. In the Institute of Metallurgy of the Ural Branch of the Russian Academy of Sciences, red mud is utilised by introducing it into the charge for the production of iron ore sinter and pellets following the use of sinter and pellets in the blast furnace charge. Metallurgical properties of sinter and pellets (reducibility, strength, softening and melting temperatures) with different contents of red mud in iron ore raw materials are also presented, including the technology of red mud usage in ferrous metallurgy carried out through industrial and laboratorial tests. Additionally, the main technical and economic indicators of blast furnace smelting (productivity, coke consumption, chemical composition of pig iron and slag, etc.) are presented. The possibility and expediency of utilisation of red mud in a blast furnace are shown.
