With the possible exception of visual sortingthis ones green, this ones not, or however the Bronze Age equivalent ranbeing able to separate minerals using differences in their density is the most ancient mineral-processing technique known to man.a Jigs The methods operate by differences in specific gravity. Jigs rely on stratification in a bed of coal when the carrying water is pulsed. The shale tends to sin, and the cleaner coal rises. The basic jig, Baum Jig, is suitable for larger feed sizes. Although the Baum Jig can clean a wide range of coal sizes, it is most effective at 10-35 mm.Mozley Multi-Gravity Separator.
