Steel can be obtained from: basic oxygen steel making: working the molten iron produced by the melting of coke and ore via blast furnaces; electric steel making: working from recycled scrap iron and/or reduction of iron ore. Melting in electric arc furnaces and ladle furnaces is ensured by control of the carbon electrodes.

Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.
Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient Iran, Ancient China, India, and Rome, but the process of ancient steelmaking was lost in the West due to the fall of the Western Roman Empire in the 5th century CE.
