One of the best sources of Rare Earth metals is in fact the toxic red slurry resulting from aluminium smelting.

Most have a trivalent electrochemistry (with the exception of Europium), and the bulk form insoluble oxides of (REE)2O3 similar to Al2O3, and Fe2O3.

As they are more electropositive than Aluminium & iron they remain as oxides during electrochemical smelting and end up in the oxide rich residue sludge.

The hard part is removing other toxic heavy metals from the sludge that will get in the way of extraction & refining such as Hg from the electrochemical refining of Aluminium.
