1) Pre-enrichment
Most Of The Black Tungsten Mines Are Of Ore Dilution Rate Over 80%. It Is Very Important To Remove The Waste Stone Before The Gravity Separation. In China, The Black Tungsten Factories Classify The Ore And Remove The Large Block Waste By Hand Because The Gangues With Ore And The Non-ore Stone Is Easy To Separate, And Their Colors Are Different.
Gravity Separation
The Beneficiation Method For Black Tungsten Is Gravity Separation Because The Density Of Black Tungsten Is Big, And Gravity Separation Can Easily Remove The Other Materials Whose Density Is Below 3.5-4, Especially For The Quartz Vein Black Tungsten. This Gravity Separation Is Much More Suitable For The Coarse Tungsten Because The Black Tungsten Is Of Large Crystals.
