【Abstract】 The application and research status of solvent extraction in oil sand separation were introduced. The principle of the selection of extraction solvent, the experimental principle of solvent extraction method, the extraction mechanism, and the factors that affecting the extraction effect were discussed. Subsequently, the single solvent extraction, the compound solvent extraction, water-assisted solvent extraction and the application of ionic liquids in the extraction experiments were introduced. According to the characteristics of various solvents, the prospect of its application in oil sand separation was analyzed, and related suggestions were put forward for the development of solvent extraction technology in the end.更多还原
