A series of laboratory-scale tests was conducted by the U.S. Department of Energy to investigate the performance of a conventional wet-drum magnetic separator for separating micronized magnetite (-10 µm) from fine coal (-600 pm). The process variables studied included feed solids concentration, magnetite-to-coal ratio, separator feed rate, and magnetite particle size. Empirical equations were developed relating magnetite recoveries and corresponding purities to the operating conditions of the device.
