 · Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically …

 · Iron smelting involves two main processes in the blast furnace: the reduction of iron from its compounds and its separation from its physical mixture with gangue materials. In a furnace, the charge is constantly moving to slow down against the force flow of the very hot gases which bring about the evaporation of moisture from the charge at the top.

 · Purification & concentration process is the process of using surface tension properly, magnetic or electrical separation to remove the unwanted impurities which are chemically combined or mixed with ore to …

The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent. The produced metallic iron contains a relatively high proportion of …
