Alluvial Gold Goldrush Mining A Clean Alluvial Gold

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.Due to the dissolution of silver that accompanies gold, chemical concentration also takes place.

The first step of the gravity process is desliming, which removes the dirt from the mineral.With alluvial gold it is actually very unusual to find a scenario where gold is so fine, that a centrifugal separator is required. The reason for putting the magnet AFTER the concentration device is so the mass flow to the magnet will less. Magnetic separators are usually low volume devices.
