摘要：

Based on a prior study on air-fluidized dense media for 6-50-mm coal preparation, this paper presents results on magnetically stabilized fluidized bed (MSFB) on fine 1-6-mm coal preparation. Magnetic stabilization improves separation by lowering the lower size limit of separation and by preventing back mixing of the separated solids. This work addresses the fluidization media characteristics, the experimental system and separation results. (C) 2002 Elsevier Science B.V. All rights reserved.
