Dry coal beneficiation with an air dense-medium fluidized bed is one of the dry coal processing methods that have proved to be efficient. In this study a (40 x 40x 60) cm air fluidized bed was employed for dry coal beneficiation tests. The effects of coal particles size and shape as well as the bed density on beneficiation process were assessed.

Dry Jigging of Coal – Ten Years allair®. Free White Paper. There are many advantages to upgrading coal with dry jigging technology. The most obvious is the lack of process water, which eliminates the need for fines dewatering and slurry confinement. Dry jigging eliminates the clean coal moisture penalty associated with wet processing.
