I don't think that is aluminum, I think it is lead.

#7 Smelting is a chemical reaction that extracts metallic elements from compounds that contain them. The metal aluminum featured here is smelted from aluminum oxide (aka alumina, where the element gets its name - originally alumium, then aluminum, with some misguided folks later deciding to make it sound more like other element names as aluminium). Alumina itself has to be refined from rocks containing an amalgamation of minerals. The most common one these days is bauxite, which is typically less than half alumina.
The only chemical reaction in this video would the oxidation and whatnot of paint on the cans. The metal itself is already elemental, and undergoes nothing but a pair of phase changes - solid to liquid to solid.
As I said, melting, not smelting.

I think the bottom of soda cans are made of another metal mixed with the aluminum, because when you take them to the scarp metal place you don't get the market price of aluminum, but a little less.
