Beneficiation of Oil Shale by Froth Flotation Critical Review

beneficiation by froth flotation. The advantages of using froth flotation may include improving pyrolysis kinetics, chemical reactivity, and saving energy by rejecting most of the inorganic gangue in oil shale matrix [14]. In this review, previous work on oil shale concentration by froth flotation will be critically reviewed.
