Electrolysis - Molten Salts

(1/1)

chelsea66:
Hi,
Does anyone know why the electrolysis of molten salt is most econonmically viable way of extracting both sodium and aluminium, but not iron???

Thank you..

jdurg:
Because chemically you really can't extract sodium and aluminum metal from their 'ores' while you can do that with iron.

Donaldson Tan:
you do electrolysis because it's the only possible chemical means of obtaining sodium. the sodium cation is practically inert to all industrial reducing agents.
