Shale Beneficiation Process

US4408999A - Coal and oil shale beneficiation process ...

Coal, oil shale and similar carbonaceous solids are beneficiated by subjecting the solids to electromagnetic radiation having a frequency between about 0.1 MHz and about 10 5 MHz in the presence of an aqueous acid solution. The electromagnetic energy enables the acid to solubilize a substantial portion of the mineral matter contained in the solids at low temperatures and pressures,

Beneficiation process for oil shale - The Superior Oil Company

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.

Bentonite - Wikipedia

Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered ...
