This paper review ed oil sand utilization worldw ide and the prospect of oil sand exploitation in China. The commercial procedures for hot water based bitumen extraction and subsequent bitumen purification w ere re viewed. Interactions of bitumenminerals, bitumenclay and bitumengas bubbles were discussed. The effect of va rious physical, chemical parameters, such as water temperature, pH value, metal ions
