Can you reduce rusted iron to pure iron?

Answer 1

Lancenigo di Villorba (TV), Italy

DRUTAZO told about SIDERURGICAL PROCESSEs (e.g. ENDOthermic Reactions). Elsewhere, I sent you the complete descriptions of Phenomena involved

C(s) + CO2(g) <---> 2 CO(g)
Fe2O3(s) + CO(g) <---> 2 FeO(s) + CO2(g)
FeO(s) + CO(g) <---> Fe(l) + CO2(g)

BIGE told about THERMITE EXPLOSIONs (e.g. EXOthermic Reactions)

2 Al(s) + Fe2O3(s) <---> Al2O3(s) + 2 Fe(l)

MY PURPOSE
At the former decades in XX century, F. Haber solved the Industrial Ammonia's Synthesis.
He discovered Pure Iron Crystals act as Catalyst able to convert Hydrogen/Nitrogen's Gas-Mixture in the Chemical Products.
HOW DID HE FORM THESE CRYSTALs?
As you asked, he thought to START FROM RUST.
He treated PURE IRON(III) OXIDE (e.g. reddish fraction of rust) in a Pressure-Reactor where he pumped Hot Hydrogen Gas-Stream against this reddish powder. In a satisfactory fashion, he obtained Metallic Crystals

3 Fe2O3(s) + H2(g) <---> 2 FeO.Fe2O3(s) + H2O(g)
FeO.Fe2O3(s) + 4 H2(g) <---> 3 Fe(l) + 4 H2O(g)

I hope this helps you.

Answer 2

If you can find a way or a chemical to reaction with rust (FeO) to remove the oxygen from it then yes. At the moment the only way I can think of is though electrochemical methods or with the aid of a blast furnace.

Edit

Yes, rust can be converted back with the aid of a blast furnace
and carbon
Fe2O3 + 3 CO → 2Fe + 3CO2

Read the chemistry part of

Answer 3

no.
you can remove rust from any iron that is left, but you cannot change rust back into Iron.

Answer 4

Not quite. You must find a way to get rid of rust. It can be done by means of some chemicals.

Answer 5

yes we can, just use the chemical called "toulene". It is a subtance that removes rust.

Answer 6

try the mysterious force known as "an angle grinder"

Answer 7

thermite process:


2Al(s)+Fe2O3(s)-->
Al2O3(s)+2Fe(s)
