Apr 14, 2015 · Recovery is a process of eliminating nongold products from gold. Gravity methods rely on separation based on mass. 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.
