Chemistry - Separating Aluminum Oxide From Impure Aluminum Chloride

For a long time I have I've had a large amount of dry & impure aluminum chloride sitting around as a biproduct of silver recovery.
I thought it would be a fun learning experience to attempt to recover pure aluminum metal from my buckets full of AlCl3, and if that worked well enough, I would attempt to extract pure aluminum from the local clay which is rich in aluminum. ( I am very aware this is not profitable and dangerous )

I am not a chemist, and for several years now I have been looking for a > simplified < answer on how I can accomplish my goals chemically.

I think I've finally found an answer, but I would appreciate it if someone who knows what they are doing can correct mistakes or maybe streamline the process.
This is part of an article I found:

The most promising of several acid processes investigated appears to be HCl leaching of the clay followed by crystallization of AlCl3·6H20 by sparging with HCl gas. To obtain Al2O3 by this process, calcined clay is leached with 26-pct-HCl, a solid-liquid separation is made, and the liquor is treated by solvent extraction to remove iron. The purified leach liquor is evaporated to increase its AlCl3 concentration and AlCl3·6H2O is crystallized by the injection of HCl gas, since AlCl3·6H2O is practically insoluble in strong HCl. The crystals are calcined to Al2O3, and HCl is recovered from the offgases. The mother liquor is heated to recover some HCl as gas; it is then adjusted to the proper acid concentration and returned to leaching.

.
From my understanding of this, I can force pure aluminum to crystalize by bubbling hydrogen chloride gas through the concentrated hydrochloric acid mixture containing the aluminum chloride.
I am not sure about the process of removing iron by "solvent extraction", but at this point I would not mind the iron impurity for my first couple experiments.



Any help would be appreciated. Thank you.

If what I am reading is correct, oxalic acid is commonly used to leach out iron.

Sound like a whole lot of unproductive, dangerous work. Exert your efforts on something safer and more rewarding.
