Placer gold gravity concentration equipment

Gravity separation is the most basic way of placer gold beneficiation.To obtain gold by washing it from sand is the gravity separation of gold from the gold placer.Because the density of the gold, in various gravity separation, gold always settle from a variety of media, and the sediment was washed away.In placer gold beneficiation process, using the jig,Shaker,spiral chute, spiral concentrator machines and other equipment can be very effective in the recovery of gold.

Gravity separation is also an effective means of recovering gold from vein gold ore.For example, the coarse gold grains disseminated gold ore, gold and gangue grinding fineness can reach full dissociation, then using only gravity chute or shaker beneficiation device processing, gold recovery can be achieved more than 70%.

Gravity separation and flotation, mixed with mercury, cyanide and other methods together to use not only be able to handle all types of gold-bearing ore, but also to improve gold recovery indicators.Example, containing metal orderly processing more to flotation, but when ores contain coarse gold, before the flotation process, you must use the jig, gravity concentration equipment for processing, in order to avoid in the futurethe sorting operations cause the loss of the gold.Spiral chute, shaking table and gravity concentration equipment is also often used to handle the flotation tailings and amalgamation tailings, so that the gold recovery is greatly improved.
 
 

Placer gold gravity beneficiation process

In gravity beneficiation process, the mineral particles is a movement in the flow medium (such as water).Each gravity separation is not a media stream work,but several media streams and some mechanical mechanism of action with the completion of the separation process.For example, in the jig beneficiation process, up and down alternating medium flow can be divided beneficiation tablets, the level of media streams can make the tailings discharge;Shaking table and spiral chute beneficiation process, the main medium flow to horizontal flow and inclined flow, but the medium flow formed in the baffle between the rise in water plays the role of important ore particles sorting.
