A novel high gradient magnetic separation (HGMS) process for particulate matter cornprizing a fluidized bed is proposed, and some of its test results are reported. A recovery of magnetic particles from glass particles is tested, and its separation efficiency is about 80%. Magnetic beneficiation of coal powder is also investigated. The residual-ash content of the removed matter is about 40%, which is very large compared with the original coal. An improvement of the residual-ash content by the electrostatic effect is also observed.
