Air-dense medium fluidized beds for separating 50-6 nim coal have been used
successfully in commercial applications in China. In this study, the autho
rs studied magnetically stabilized fluidized beds for separating fine coal
(6-1 nun). The magnetic stabilization enhances the separation by preventing
back mixing of the feed solids. This paper discusses the principle of coal
separation in magnetically stabilized fluidized beds, the experimental sys
tem, and the separation results. (C) 2001 Elsevier Science B.V. All rights
