Compare High-G & Low-G Centrifugal Concentrators - Gravity,
Unliberated gold, which is associated with oxide, silicate, or sulfide gangue particle and for which the average particle density is substantially lower than that of gold. Flakey, Hydrophobic gold particles are highly likely to go unrecovered to tailings using a low-G concentrator.Day 71, PLACER GOLD RECOVERY METHODS Xi, a review | Rio,The concentrator is portable and easy to use, and it efficiently recovers fine gold. It is relatively inexpensive and requires little maintenance. The smaller machines are suitable for exploration or mineral concentration for small placer deposits.Spiral separator ,Spiral concentrator ,Walker Mining,Spiral separator also called Spiral chute is one of low investment gravity separating machine with high processing capacity.Compared with shaking table ,gold shaking table ,jig separator , spiral separator have advantages like: high processing capacity, low cost , energy saving ,user friendly,long lift span. it is widely applied in alluvial gold ,chrome,tungsten,Tin mining plant in Africa,Asia.
