Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 5070% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...

Steel production causes significant emissions of carbon dioxide. To decarbonize steel production and its high carbon dioxide emissions, Fraunhofer researchers, TS ELINO and Salzgitter AG are working on converting an existing steel mill to climateneutral production methods. The aim is to produce steel by the direct reduction of iron ore with hydrogen, which would completely replace ...

In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.

STEEL MANUFACTURING IN AUSTRALIA. Steelmaking begins when iron ore is smelted to produce metallic iron, which is then converted to steel by removing excess carbon and adding various alloys in a Basic Oxygen Furnace. It is then continuously cast and rolled into a variety of shapes and sizes. Hot rolled steel is produced for various uses; ...

The BOF process uses 30% of recycled steel, while EAF uses up to 90. This is a far more sustainable option instead of mining more iron ore as a fresh ingredient in the steelmaking process. There is also an alternate steelmaking process called HIsarna ironmaking. In HIsarna, iron ore is processed immediately into hot metal.
