Abstract

We measured the removal efficiency of hematite (Fe₂O₃) and iron (III) hydroxide (Fe(OH)₃) fine particles suspended in water in a high gradient magnetic separation (HGMS) system. Fe₂O₃ and Fe(OH)₃ have relatively small magnetic relative susceptibilities (MKS) near 10^-3 and average particle diameters near 1 μm. We demonstrated that HGMS is able to effectively separate weakly magnetized particles.
