Modernday steel production makes use of both traditional raw materials (iron) and recycled materials to turn them into steel. With this in mind, here are the 6 steps to modern steel production explained. Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made.

While limestone may seem unrelated to the production of iron and steel, it actually is an essential auxiliary material that is added during the production process. During the process of reducing iron ore, it is necessary to remove the silica, alumina (Al 2 O 3), and other nonferrous components contained in iron ore. The added limestone fuses with these components and lowers their melting point, making it .

The Midrex process contributes to the biggest share of the directly reduced iron (DRI) produced, which corresponds to about 60% of the world production [12, 13, 20]. Today, the DSR process (Route 3) which produces molten iron has not made a pronounced contribution to iron production compared to the previous two routes.

Beneficiation of Iron Ore. This also applies to iron ores of the nonmagnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500mesh for liberation of the iron minerals from the siliceous gangue.
