Placer gold ore dressing process is simple, usually through screening, gravity separation, cleaning separation can obtain good quality gold. But placer ore contains only a small amount of gold, is very limited, how can we ensure the return on investment of gold mining? This requires high performance, energy-efficient, large capacity, high recovery rate of dressing flow chart and dressing equipment.
We use a process flow through jig machine for rougher, centrifugal concentrator for scavenger, shaking table and algamation for cleaner, ensure the capacity and the recovery rate at one time, Only in this way we can ensure economic benefit of dressing process of low grade gold ore. First, use wheel loader feed raw ore into trommel screen (or rotary scrubber) to remove rock and gravel, avoid rock and gravel into the jig machine effect the performance. The small sand which removed rock and gravel feed into the jig machine for gold separation, the rough concentrate get from jig machine feed into shaking table, after that the gold concentrate is produced. The tailing of jig machine put into vibrating screen to remove the sand bigger than 1mm, to guaranteed the feeding size reaches the best effective separation size range of centrifugal concentrator. The action of centrifugal concentrator scavenge the tailing of jig is to raise gold recovery for the whole process flow, to collect fine gold, flake gold which lost from jig machine as much as possible. The concentrate of centrifugal concentrator through algamation to obtain gold.
