If I get aluminum scraps and dissolve it in hcl how do I turn it back into metal and what reactions are happening there? Also is there a chemical that I can rinse through sand to dissolve iron because I found this sand that has tons of iron(I checked with a magnet)

2Al (s) + 6HCl (aq) -> 2AlCl₃ (aq) + 3H₂ (g)

 

Metallic Aluminium can be produced by electrolysis of molten Aluminium Chloride (>= 700 C temperature).

2AlCl₃ -> 2Al + 3Cl₂ (g)

Then why not use magnet or better electromagnet?

There can be also used centrifuge.

"Centrifugation is a technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed."

Centrifuges cost too much, i dont use a magnet becase the sand sticks too the iron which is annoying to remove
