High gradient magnetic separation for weakly magnetized fine particles (for geothermal water treatment)

Okada, H. / Tada, T. / Chiba, A. / Mitsuhashi, K. / Ohara, T. / Wada, H.

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 mu m. We demonstrated that HGMS is able to effectively separate weakly magnetized particles.
