Fine coal (6–1 mm) separation in magnetically

2001-12-1  Air-dense medium fluidized beds for separating 50–6 mm coal have been used successfully in commercial applications in China. In this study, the authors studied magnetically stabilized fluidized beds for separating fine coal (6–1 mm). The magnetic stabilization enhances the separation by preventing back mixing of the feed solids.

Coal dry beneficiation technology in china: the state

2003-6-1  In China, coal is the major source of energy and its leading role in energy consumption would not change in the next 50 years. Coal preparation is the essential component of Clean Coal Technology. In China more than two-thirds of available coal reserves are in arid areas, which results in the unfeasibility with conventional wet processing for coal preparation.

A PRELIMINARY COMPARISON OF COAL

Coal can be simply classified by applications into two categories: i) thermal coal used to provide heat energy in combustion, and ii) metallurgical coal which is converted to coke, in a carbonization process, and used mainly in the iron and steel industry. Metallurgical coal contains even higher heating values than thermal coal.
