Electrolysis in Ironmaking

Process Route

Iron dissolutionIron ore fines Hydrochloric Acid

Solid separation Sludge

FeCl2 soln.

Chlorination Chlorine gas

Crystallization

Extra chlorine to be sent to chlorine

chamber

FeCl3 soln.

Solid FeCl3 crystals

Electrolysis of molten FeCl3

Iron at cathode

Reactions

Fe2O3(s) + 6HCl (l)=2FeCl2 (aq) + 3H2O

2FeCl2 (aq) + Cl2 (g) = 2FeCl3 (aq)
