4.1. Fluidized separation with dense medium technology. Air dense medium fluidized bed (ADMFB) separation is the most widely used technology for dry-type coal cleaning with the efficiency comparable to those of wet-type methods. In an ADMFB, a solid medium transforms from a packed bed to a fluid-like state by an upward air stream.
