Due to the dissolution of silver that accompanies gold, chemical concentration also takes place. For this reason, alluvial gold is poorer in silver content compared to strand gold. Under the action of infiltration waters, a separation of grains and golden sheets is produced, which from the surface, gradually descends to the base.

The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction (where the gold is found) from the larger mineral fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the mineral fraction.
In the lab, this process is called "gravity separation.". Sluice boxes are designed to mimic this naturally occurring gravity separation. As water carries gold-laden sediment through the box, small obstructions called riffles block the free flow of material. These tiny flow restrictions form low pressure pockets where the gold collects.
