ABSTRACT:
Tar sands and like mineral solids-plus petroleum deposits are separated into a petroleum fraction and a solids fraction by contacting with an organic solvent or diluent (in one or more stages) to give a liquid slurry, providing in the system a small amount of an aqueous agglomerating liquid, mixing and agitating until discrete compact agglomerates of hydrophilic solids form, separating the solid easily-handled agglomerates and recovering the petroleum fraction and solvent or diluent. This process avoids the large volumes of aqueous effluent inherent in the "hot water" and other processes using large amounts of water. The solid agglomerates may be used as clean fill, sintered to aggregate, or modified to serve as soil amendments.
