Abstract: Oil sand is a kind of unconventional fuel resource. The hot water-based extraction is the most common way to recover bitumen from oil sands. In this research, the oil sand samples from Houba, Sichuan, and Tumuji, Inner Mongolia, were conducted using the hot water-based extraction method. Microscope observation, XDR analyses, specific surface area and pore volume of oil sands were applied to qualify the lithology of different samples. The bitumen recoveries of the hot water-based extraction were correlated to the lithologic characters of the oil sands. The result shows that factors, such as contents of clay minerals, cementation manner and degree, grain sizes of minerals, and the degree of weathering, may affect the bitumen recovery efficiency from oil sands using the hot water-based extraction. These factors should be taken into account in process design for bitumen recovery from oil sands.
Keywords: oil sands lithology hot water-based extraction bitumen recovery
