Hindered-bed separators can concentrate particles based on size, density and shape. With feed stocks having a relatively tight size distribution, separations based on density and shape can be successfully achieved.

Common applications include removing rock (SG 2.65) from coal (SG 1.35), upgrading iron ore, and the removal of silica from heavy-mineral concentrates. In addition, minerals such as mica can be separated from ores such as phosphate and sand due to its flat shape.
