酸性体系中钼的溶剂萃取研究进展

Research advances of molybdenum solvent extraction in acidic system

目前酸浸工艺已广泛应用于各种含钼物料的处理,而由含钼酸浸溶液中萃取分离钼已愈来愈受到关注.文中在综述酸类萃取剂、中性萃取剂、胺类萃取剂从酸浸液中萃取分离钼工艺研究现状的基础上,对各类萃取剂萃钼机理及优缺点进行了分析,并指出了进一步研究的方向.

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.
