Abstract

See full text

A method for producing aluminum includes: a dissolution step of dissolving a hydrate containing Al in water to prepare an aqueous solution that contains Al ions; an extraction step of bringing an organic phase that is composed of an extractant into contact with an aqueous phase that is composed of the aqueous solution to extract the Al ions in the aqueous phase into the organic phase; and an electrodeposition step of electrolyzing the organic phase as an electrolytic solution to electrodeposit metallic Al onto a surface of a cathode from the Al ions in the electrolytic solution.
