Electrolysis - Molten Salts
« on: March 17, 2005, 11:34:36 PM »
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..

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

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.
