    摘要: A process for beneficiating oil shale is disclosed including the steps of grinding the shale to fine particles in an aqueous medium, portions of which are kerogen-rich and kerogen-poor, scrubbing the particles, conditioning using a collector and a frother, and separating using froth flotation and oil agglomeration/dewatering.
