Sep 23, 2017 Steel-smelting slags form a large proportion of metallurgical wastes. They are generated at a rate of 150200 kgt of steel, on average. At current rates of steel production in Russia, the annual output of smelting slag is 9 million t, of which 811 consists of metallic iron and 1540 of iron oxides. The total iron content in the slag is 2030 wt .
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
