Abstract:

As China’s industrialization advances, the demand for molybdenum continues to grow, leading to an expansion in mining and a corresponding increase in molybdenum tailings. These tailings not only occupy significant land but also pose environmental risks, such as pollution and geological hazards like dam breaks and debris flows. Despite these challenges, molybdenum tailings remains a valuable resource, rich in minerals with promising potential for comprehensive utilization. This paper analyzes the distribution of molybdenum ore resources and the composition characteristics of molybdenum tailings, highlighting the necessity and feasibility of their comprehensive use. It introduces the recovery of valuable minerals, including feldspar, calcite, molybdenum, tungsten, and iron from molybdenum tailings, and reviews their applications in construction, agriculture, mine filling and other aspects. While recoverying valuable metals does not fully address the surplus of molybdenum tailings, large-scale applications in building materials and tailings filling are possible. However, the effectiveness of these materials depends on performance metrics such as strength, wear resistance, and durability, while agricultural applications must also mitigate heavy metal pollution.

Key words: comprehensive utilization of resources, recovery of valuable minerals, heavy metal pollution, molybdenum tailings, molybdenum ore
