Question

extraction of iron from hematite

Answer 1

Hello!!


➡Iron is extracted from its ore,hematite,by reduction with carbon.
➡This takes place in a blast furnance, after blasts of air (20% oxygen) heated to 1000 degree C, which are blasted into the bottom.
➡The coke is oxidised to carbon dioxide.
➡The carbon dioxide reacts with coke to form carbon monoxide.
➡Iron oxide in the ore is reduced to iron by the carbon monoxide.
➡The iron falls to the bottom of the blast furnance where it melts.
