ChemicalReactions Posted May 24, 2018 Posted May 24, 2018 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)

There can be also used centrifuge. https://en.wikipedia.org/wiki/Centrifugation "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."
