Metallic iron is carbonized by carbon in the coke and CO gas and melts at 1200–1300 °C. Molten iron and slag drip down through the coke layer to the hearth where they reach their final temperature and composition.

Processes and Procedures in the Extraction of Iron ...

15-02-2021  The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

2 Steel Industry: Production Processes

chemical reactions. In iron ore, iron is presents in its oxidised form. In iron reduction processes, a reducing agent, based on carbon or hydrogen, removes the oxygen from the iron. This removal can take place either above or below the melting point of the ore and the reduced iron. Reduction above the melting point results in pig iron.

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.
