Iron and Steel Slag Statistics and Information

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. From this and the added fluxing agents molten slag and iron are formed.


Introduction of iron ore. Steel slag is a by-product of the steelmaking process. It is composed of various oxides oxidized in the smelting process by impurities such as silicon, manganese, phosphorus and sulfur in pig iron and salts generated by the reaction of these oxides with solvents. The mineral composition of steel slag is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and

An Introduction to Iron Smelting Part I Theory Harald

May 20, 2017 The smelting, or reduction, of iron ore is a thermochemical reaction, wherein the iron oxides are reduced to metallic iron. Impurities in the ore are melted out of the ore in the form of slags most commonly iron silicates while the iron itself is never truly molten. Instead the product of the smelt is a spongy mass of iron and slag known as a bloom. This then needs to be consolidated by


CaO now reacts the impurities of ore called GANGUE to form slag. Slag is the mixture of CaSiO 3 and CaAlO 2 2. The slag floats over the top of molten iron. Slag is a useful byproduct. It is used in road making, cement manufacturing a light weight building materials.
