The particles must have nearly equal size and different mass to be separated. There is a limit to the process of screening to smaller and smaller particle sizes during the recovery of gold.

Gold Well Vortex Drop Riffle Sluice Box

In all the tests done so far, even unclassified materials, the recovery rates are still in excess of 95% for most gold. In some tests involving crushed ore from a vein, where the gold was 400 mesh and finer, the recovery was around 80% but that was due to the fact that gravity type systems do not typically do well in recovery of gold that is so
