摘要
金属钼作为一种稀有金属,在含钼的废弃物中回收钼,不仅可以降低钼矿的开采率,也可以将废弃物进行有效利用。介绍了对含钼废弃物进行回收的必要性,以废催化剂、选钼尾矿和含钼废水为主要回收原料,列举了多种不同回收金属钼的方法,如:Na2CO3焙烧-水浸取法、焙烧-有机物萃取法、溶剂萃取法、离子交换法等。并且比较了这些方法的优缺点,其中Na2CO3焙烧-水浸取法和离子交换法的钼回收率更高且对环境友好。综述了回收金属钼的研究现状,对我国钼产业及钼回收工艺流程的研究发展进行展望。
As a rare metal,metal molybdenum recovers molybdenum from molybdenum-containing waste,which not only reduces the mining rate of molybdenum ore,but also makes effective use of waste.The necessity of recycling molybdenum-containing waste is introduced.The waste catalyst,molybdenum tailings and molybdenum-containing waste water are the main raw materials for recycling.A variety of different methods for recovering molybdenum are listed,such as Na2CO3 roasting-water leaching method,calcination-organic extraction method,solvent extraction method,ion exchange method.The advantages and disadvantages of these methods were compared,in which the Na2CO3 roasting-water leaching method and the ion exchange method have higher molybdenum recovery rates and are environmentally friendly.The research status of recycled metal molybdenum is reviewed,and the research and development of molybdenum industry and molybdenum recycling process are prospected.
