I'd like first to apologyze if my spelling and/or syntax is sometimes hard to understand, i'm not used to english language, well let's go:
My question is purely technical. I'd like to know how to efficiently separate molten iron from aluminium oxide in a thermite reaction:

        2Al + Fe2O3 <> Al2O3 + 2Fe
I'd like to know how to avoid them from mixing after melting for the iron to be as pure as possible.

Thanks

In this situation it helps to consider an ice cube. As the ice cube forms, the water crystallizes from the outside in, as the water assumes it's crystallline structure it pushes impurities(air, salts etc...)toward the middle. The easiest way to separate the pure iron is by using a seed crystal of pure iron and slowly cooling the molten solution so that the iron expands around the seed crystal pushing all of the aluminum oxide out of the iron crystal. The key is slowly cooling the molten solution around a pure seed crystal.

Great! Thanks i'll try that.

Don't try this at all! This is a horrendously dangerous experiment to control.

This is not a method of obtainig pure iron. But ein spite that the iron will be relatively pure since it melts during this reaction (compare demsities of oxides and iron !)
