Research on the Properties of Tungsten Ore and Mineral Processing Technology
This study conducted a detailed study on the ore properties and beneficiation process of a quartz vein belt type tungsten mine in the northwest region of Gansu province.The chemical analysis of the ore shows that the WO3 content is about 0.3%,reaching the lowest grade for industrial mining,accompanied by a lower content of silver element.The tungsten phase analysis determined that scheelite is the dominant tungsten mineral in the ore,accounting for the main proportion of the total WO3.The analysis of mineral composition and distribution characteristics shows that the ore structure is simple,mainly composed of scheelite and pyrite,and the associated minerals are mainly molybdenite and garnet,which is helpful for effective separation in the beneficiation process.Research on mineral processing technology indicates that the combination of gravity separation and flotation can effectively recover tungsten ore.The structural analysis reveals that the ore body is mainly composed of vein like and impregnated structures,providing a basis for the optimization of subsequent beneficiation processes.
