I thought that electrolyzing Vitriol of Clay yields Alumina itself, but the majority of Aluminium definitely exists in the Refined Bauxite instead of the Vitriol. With Bauxite as a Layer Ore (=massive reserves and easy extraction), perhaps it’s even feasible to toss away the Refined Bauxite, and only use the Vitriol, if you really want to be that wasteful.
