Beneficiation process for oil shale
A beneficiation process for increasing the oil content of clay-bearing oil shale ore wherein the oil shale ore is subjected to an aqueous medium, agitated to disintegrate at least a portion of the clay, and the disintegrated clay is separated from the remaining oil shale to yield an oil shale having a greater amount of recoverable hydrocarbon values per ton than the unprocessed oil shale ore.

Coal Beneficiation
Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.
