Keywords coal preparation, dry beneficiation, fluidized bed 1. Introduction In China, coal is the major source of energy and its leading role in energy consumption would not change in the next 50 years (Shi, 1995). More than 80% of coal is directly burned. As a result, the emission of 70% smoke/ dust and 85% SO 2 comes from coal combustion.

Dry beneficiation of coal with an air dense-medium fluidized bed is an efficient coal separation method, which uses a gas-solids fluidized bed as the separating medium, contrasting with the conventional methods of coal preparation using water as medium as in jigs. The air dense-medium fluidized bed also differs in principle from …
Dry coal beneficiation is an effective technique to realize coal separation and upgradation, as it does not consume water, has a low cost and is pollution-free. In this study, an air dense medium fluidized bed (ADMFB) and FGX separator were arranged in series to achieve 100–0 mm coal size dry separation. Raw coal (100–50 mm and 50–0 …
