27/09/2021· The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

Iron Removal by physical-chemical ways Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe (OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe (OH) 3 ).

They are the starting materials for the technical extraction of pig iron in the blast furnace. The blast furnace operates at 1900 °C in order to smelt iron from iron ore. To attain that temperature, coke (and not coal) is used as fuel, and the fire inside the furnace is fanned with hot air at 1200 °C to 1300 °C degrees.

Impurities in the iron from the blast furnace include carbon, sulfur, phosphorus and silicon. These have to be removed. Removal of sulfur Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulfur reacts with it to form magnesium sulfide.

Extraction of iron is a lengthy process which commences from Concentration through calcination roasting. Water and other volatile impurities like sulfur and carbonates are removed by the process of Concentration. The concentrated ore is blended with limestone (CaCO3) and Coke and fed into a blast furnace from the top.

Dip the head of a match in water to moisten it. Roll the damp match head first in sodium carbonate powder, then in iron (III) oxide powder. Hold the match in a pair of tongs. Put the head of the match into a blue Bunsen flame (air-hole open). The match will flare and burn. Do not allow the match to burn more than half way along its length.
