Iron Ore Processing: From Extraction to Manufacturing
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Precipitated Calcium Carbonate
Calcium carbonate, which is also recognized as the chemical formula CaCO 3, makes up almost five percent of the earth's crust and is found all throughout the planet.CaCO 3 is a combination of CaO (calcium oxide) and CO 2 (carbon dioxide). Calcium carbonate's most common natural forms are chalk, limestone, and marble.
Lime, an essential component in the steel industry
Phosphorus removal: Phosphorus, contained in the iron ore and the scrap metal that are used to start the steel-making process, can seriously damage the properties of steel.In large quantities, it lowers the ductility of the steel making it easy to fracture when it is cold-worked. Quicklime added to the metal-making process extracts the phosphorus in the …
