Abstract: The acidic leaching process has been widely applied to the treatment of the materials bearing molyb - denum for the recovery of molybdenum. Moreover, there has been a growing concern on the separation of molybdenum from acidic leaching solutions by solvent extraction. Based on the review of the current research status on acidic, neutral and amine extraction agents that are used in the molybdenum extraction technique from the acid leaching solution, the extraction mechanisms of the various agents and their relative merits are analyzed, and the trend of further study is prospected as well.
