Description/Abstract This paper describes a derogen agglomeration method for beneficiating oil shale.^It comprises: comminuting a substantial portion of the oil shale to a top size of about 0.4-0.003 inch in the presence of an added liquid consisting essentially of an organic liquid; contacting the oil shale with a multiphase liquid comprising an added organic liquid and water to form kerogen-rich agglomerates and mineral-rich particles; and separating the kerogen-rich agglomerates from the mineral-rich particles.
