Not really. It works by loading up with magnetite and iron forming like little riffles. The little gold particles get embedded in the magnetite. You keep running until it fairly loads up with gold. It will catch some really small gold. I met with the inventer "patent holder" and saw him futher concentrate and do a clean up.

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

This process uses a vacuum to remove air from the leached solution and mixes zinc dust in with the gold, which allows it to more easily separate from the rest of the solution. The separated gold-zinc-dust combo is then mixed with sulfuric acid to dissolve the zinc, and the solution is filtered again, leaving behind just the desired gold pieces.

In comparison, fine gold, as well as gold flour and dust, can fit through small openings, such as the ones of a 40-mesh screen. These can be as small as 0.4mm (0.01in) . The tiny size of such particles makes their recovery much more challenging than what you would experience while prospecting for nuggets.
