Method for reducing molybdenum back extraction three-phase substances

The invention belongs to the technical field of hydrometallurgy, and particularly relates to a method for reducing molybdenum back extraction three-phase substances. The method comprises the following steps that 1, ore pulp obtained after molybdenum ore is subjected to acid leaching is pretreated; step 2, molybdenum extraction; 3, the molybdenum-loaded organic phase obtained in the step 2 is subjected to molybdenum back extraction through a novel back extraction agent; and 4, obtaining a qualified molybdenum product. The method can effectively reduce the generation amount of the three-phase substances, and solves the problems of phase splitting difficulty and metal loss caused by the generation of the three-phase substances in the molybdenum reverse extraction process. 本发明属于湿法冶金技术领域，具体涉及一种降低钼反萃取三相物的方法。本发明包括如下步骤：步骤1、将钼矿石酸浸后的矿浆预处理；步骤2、钼的萃取；步骤3、对步骤2得到的钼负载有机相，改用新型反萃取剂进行钼的反萃取；步骤4、得到合格钼产品。本发明能够有效地降低三相物的产生量，解决钼反萃工艺中应三相物产生导致的分相困难、金属损失问题。
