The demo works because the microwaves energize the metals in the silicate slag, mixing and draging them along where they begin to settle out in layers according to weight.
What he's calling "monoatomic gold" in the black sands and magnetite are actually Iron Pyrite which occurs any time you react iron with sulfur (acid rain anyone?). Some black sand does have about 0.00003% gold in it though, but the energy consumed by the microwave and the resources consumed in the flux are going to cost more than the gold you do extract. Furthermore, this process is more likely to produce pyrite than gold.
The reason his "gold from beer bottles" is a different color isn't because it's gold mixed with rhodium or platinum as he explains, but because iron and chromium are used to give the beer bottles their color. These are reacted with sulfur to produce pyrite.
His theory is crackpot.

All things being equal, the simplest solution is usually correct. :D
