Research Progress on Comprehensive Utilization of Molybdenum Tailings

A large number of tailings are produced in the process of molybdenum ore separation, and the tailings accumulate and occupy a lot of land, which has hidden dangers and has an adverse impact on the ecological environment. The research progress of molybdenum tailings in resource utilization and material utilization is reviewed. Molybdenum tailings contain many valuable metals such as tungsten, molybdenum, copper and iron, as well as non-metallic minerals such as rutile, quartz and feldspar, which can be recycled to improve resource utilization. Gangue minerals such as quartz and feldspar in molybdenum tailings are the main components of natural building aggregates. Unfired bricks, ceramics, glass-ceramics, gel materials, cement and concrete and other new materials can be prepared from molybdenum tailings. Trace metal elements in molybdenum tailings are nutrient elements for plant growth and can be widely used in agriculture. The comprehensive utilization of molybdenum tailings meets the national requirements for the treatment of "three wastes" and environmental protection, and is of great significance to solve the problem of massive accumulation of molybdenum tailings at present.
