In response to the issue that traditional beneficiation processes and direct leaching methods are difficult to achieve economically effective recovery for a certain low-grade and refractory molybdenum oxide ore, based on its process mineralogical characteristics, the application of superconducting magnetic separation for pre-enrichment of the low-grade and refractory molybdenum oxide ore was studied. The effects of magnetic separation conditions such as background magnetic field strength, slurry flow velocity, separation slurry concentration, slurry feeding method and other magnetic separation conditions on the pre-enrichment concentrate indicators were investigated. The results show that by adopting the upper feeding method and under the suitable conditions of background magnetic field strength of 4 T, slurry flow velocity of 0.025 m/s, and separation slurry concentration of 10%, the pre-enrichment concentrate has Mo grade of 0.75% and recovery rate of 64%. Through theoretical calculation and recovery mechanism analysis of the magnetic separation recovery process, a high-efficiency separation scheme is optimized and designed, which includes coarse (-0.5 mm+0.025 mm) and fine (-0.025 mm) particle size classification and separation processes, as well as the coordinated matching of high magnetic field strength (5 T) and high flow rate (0.04 m/s). The final process indicators are:Mo grade in the concentrate of 0.88%, recovery rate of 63.79%, and enrichment ratio of 3.95. The method can achieve the goal of efficient pre-enrichment of low-grade and refractory molybdenum oxide ores, meet the feed grade requirements of subsequent leaching processes, and has certain application potential.

针对某低品位难选氧化钼矿采用传统选矿工艺和直接浸出工艺难以实现经济有效回收的问题，根据其工艺矿物学特性，研究了采用超导磁选工艺对某低品位难选氧化钼矿进行预富集，考察了背景磁感应强度、矿浆流速、分选矿浆浓度、矿浆进料方式等磁选条件对预富集精矿指标的影响。结果表明：采用上部进料方式，并在背景磁感应强度4 T、矿浆流速0.025 m/s、分选矿浆浓度10%适宜条件下，预富集精矿Mo品位为0.75%、回收率为64%。通过对磁选回收过程的理论计算与回收机制分析，优化设计了粗（-0.5 mm+0.025 mm）、细（-0.025 mm）粒级分级分选工艺与高场强（5 T）和高流速（0.04 m/s）协同匹配条件下的高效分选方案，得到最终工艺指标为：精矿中Mo品位0.88%，回收率63.79%，富集比3.95。该法可实现对低品位难选氧化钼矿进行高效预富集的目标，能满足后续浸出工艺的入料品位要求，具有一定应用潜力。
