Investigation of Combination of Variable Diameter Rod Elements in Rod Matrix on High Gradient Magnetic Separation Performance

Abstract

Rod matrix is effectively applied to separate fine weakly magnetic particles in pulsating high gradient magnetic separation (PHGMS), due to its reliable operation, simple combination and resistance to mechanical entrainment. They are now used to beneficiate oxidized iron ores, ilmenite, and wolframite, etc., and to purify wastewater. The combination of variable diameters rod elements in rod matrix plays a decisive role in recovery most of the different size fractions of magnetic particles, thus generating a significant influence on the performance of PHGMS. Combination of variable diameter rod elements in rod matrix on PHGMS is investigated in combination of 3 mm and 2 mm rod elements in rod matrix, by Slice-Matrix Analysis (SMA); it was found that the recovery of combinatorial rod matrix is higher than single diameter of matrix on PHGMS.
