Abstract:Molybdenite (MoS2) is an important molybdenum-bearing ore. At present, about 80% of molybdenum comes from this kind of resources. In industry, flotation-pyrometallurgical process is usually used to produce molybdenum metal. However, this traditional process is easy to produce SO2 and cause environmental pollution, and there are some problems, such as low recovery rate, difficult to deal with low grade ore and so on. In contrast, hydrometallurgy has attracted much attention because of its advantages such as economy, environmental protection, high efficiency and so on. For this reason, the development and prospect of molybdate leaching technology in recent years are comprehensively analyzed, and the advantages and disadvantages of different molybdenum separation and extraction methods are compared. It is pointed out that leaching is the core of future development for molybdate hydrometallurgy technology. Developing new technologies and optimizing conditions to achieve efficient molybdenum leaching, shortening the process and achieving industrial application, and improving the synchronous recovery of associated resources will become the key research direction.
