There would be a huge oxide layer on those screens, probably paint too.
I've seen them turn to dust in my hands before.


The Ali oxide needs cryolite to turn it back into Aluminum & thats expensive as well as toxic.
Might as well make Ali from Aluminia.



Some stuff I know it isn't worth it so I let it go free, like tinned copper.
For 100Lb's of copper I'd get less then a Lb of tinned.
