The Gold Sluice Box works with the gold trommel screen to recover the gold roughly. The idea is that the bottomsizes of gold trommel go through the sluice box. The gold particles will be trapped by the grass mat because of the large specific gravity of gold. The Gold Sluice Box works with the gold centrifugal concentrator to recover the gold from the tailing of the concentrator.
The idea is that the tailings of gold concentrator go through the sluice box with mat and the mat would trap the gold particles.
This process could avoid the gold losing effectively.
