  • Application of Hydrocyclone in Gold Ore Tailings

    Before the gold mine tailings are concentrated in the thickener, it will separate coarsegrained tailings that are easy to concentrate from the tailings by cyclone, and then the hydrocyclone overflow is sent to the thickener for concentration In this way, it not only can get highdensity grit and improve the tailings processing capacity, but also can reduce the load of the thickener andAs gold mining is an expensive exercise, opportunities for lowcost gold production need to be found, which is spurring the retreatment of tailings, says Stateowned Mintek’s Minerals ProcessingGold tailings retreatment an attractive Mining ResearchWe select the best high grade, sweet spot mining claims in prime areas of historically known successful gold mining districts The project sites have immense above ground tailings piles that can be readily processed Large mining projects or major ore mill processing plants, where the best ore from 100's of miles around was shipped, operated on these sites Additional projects are beingPrecious Metals Reclamation Mining Company
