alluvial sand washing plant

alluvial sand washing plant is a gravity separator line, Gravity separation also called gravity concentration, which is a mineral processing method for separating minerals according to different mineral densities. 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.

Product Description

Working Principle:

For alluvial gold ore, we do not need to crush and grind the ore. The general processing flow is usually:

1st. Screening and washing (trommel screen). We always use the trommel screen to wash the raw ore and remove the barren rocks and gravels.

2nd. Enriching (Gravity separation equipment). The gravity separation equipment such as the centrifugal concentrator, spiral chute, jig machine, are always applied at this process to enrich the heavy minerals.

3rd. Roughing, scavenging, and cleaning. We usually apply the shaking table for concentration after the 2nd step.

4th. Refinery. We could use the gold melting furnace to smelt the gold sand into shape lastly.
