The Step-by-Step Process of Producing Iron from Iron Ore
The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).

Steel making process – ArcelorMittal
Iron ore can be found all over the world, but its iron content varies. Steel scrap has been selectively collected for several decades and is recycled as a valuable raw material for steel production. In the steel production, following stages are identified: production of pig iron; production of liquid steel; hot rolling and cold rolling

Iron Ore Pelletization
Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

Iron Ore Smelting Process
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being
