Concentration Criterion of Ore

where E is the criterion index for the concentration criterion of ore.ρ 1 ′ and ρ 1 are, respectively, the density of high-density and low-density minerals in ores to be separated. ρ is the density of the mediums. When E > 2.50, the separation can be easily conducted, and the lower limit of the effective separating particle size can reach 0.019 mm.
