The electrochemical effect of an electric current brings about the reduction of metallic compounds, and thereby the extraction of metals from their ores (electrowinning) or the purification of the …

The furnace is filled at the top with the iron ore oxide most commonly hematite ((Fe_2O_3)) but can also magnetite ((Fe_3O_4)), carbon called coke and limestone ((CaCO_3)). For the purpose of this discussion the iron ore oxide hematite ((Fe_2O_3)) will be shown. ... This final purification step removes much of the impurities and the ...

Pig iron, an intermediate form of iron produced from iron ore and is subsequently worked into steel or wrought iron 10. Uses: Traditionally pig iron would be worked into wrought iron in finery forges, and later puddling furnaces, more recently into steel. In these processes, pig iron is melted and a strong current of air is directed over it ...

2. Introduction To Pelletisation Process Pellets are spherical balls formed by the agglomeration of natural or ground iron ore fines in the presence of moisture and binder These green balls of 5 – 20mm size are then dried, preheated and fired at 1250 – 13500 C Bonding is developed between the fine ore particles at such high temperatures Additives like Bentonite, …

Iron ore isn't pure iron oxide – it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide.
