mainly two processes: i) oxygen steel making and ii) electric furnace (in a ratio of 71:29). The consumption of scrap is about 900 kg from a total metallic charge of roughly 1080 kg for producing one tonne of liquid steel through electric arc furnaces. In oxygen steel making, about 20 to 25% of the charge is scrap which act as coolant.

The overall production process inside the kiln requires a duration of 10-12 hours during which the iron ore is reduced and discharged to a rotary cooler for cooling below 1000C, to prevent reoxidation and effect a better separation of non-magnetic from sponge iron. The process of sponge iron making aims to remove the oxygen from iron ore and when the same occurs, the departing oxygen causes micropores in the ore body making it porous. .

The blast furnace is charged from the top with a burden. This consists of alternate layers of coke and a mixture of sinter and/or pellets, lump ore and fluxes. In the furnace, the iron ore is increasingly reduced and liquid iron and slag are collected at the bottom of the furnace, where they are tapped from.

Iron ore generally contains chemicals that have to be removed. Therefore, iron ores have to be processed into sponge iron with high iron content. Sponge iron (Fe) is the product of reduction of pellet or iron ore. In the reduction process, iron ore pellets (Fe2O3 and Fe3O4) and liquefied natural gas (CH4) and water steam (H2O) are put in a reactor.
