Fine Gold Recovery. Separating Placer Gold Particles from

Even after final processing, you will still find that you concentrates, which are now "super concentrates", will still have a mix of fine gold and fine black sand particles. Here is where the magnetic nature of black sands will help us in the final separation process. Using a rare earth magnet, we can physically pull them away from the gold.
