Research Progress on the Application of Preconcentration Tailings Discarding Technology in Tungsten Beneficiation

Abstract
With the further exploitation of tungsten resources, the ore dilution rate increases year by year, the WO3 grade of raw ore decreases, dissemination size becomes finer, the easy ore becomes increasingly scarce, and the tungsten resources are poor, fine and difficult to handle. Due to the change of ore properties, the waste rock rate of the original hand sorting decreased year by year, resulting in the increase of grinding pressure and mineral processing cost. At the same time, it is difficult to recruit workers and affect production. Ore preconcentration is one of the important means to save energy, reduce emission and improve the "three rate" index in the field of mineral resources. It can be applied to tungsten ore preconcentration to improve the selected WO3 grade, so as to solve the bottleneck problem of restricting the reduction of workers in mining enterprises, expanding production, reducing cost and increasing efficiency, and to meet the requirements of large-scale industrial mines on mineral processing technology. In this paper, the preseparation methods of ores, such as radiation picking and heavy medium beneficiation, and their application progress in tungsten resources are emphatically introduced. Finally, it is pointed out that the development, processing and utilization efficiency of tungsten resources can be greatly improved only by developing and utilizing efficient and intelligent ore preseparation technology, equipment and process on the basis of scientific and technological progress. It is also pointed out that the combined process of radiation sorting and heavy medium beneficiation is an inevitable trend in the development of ore preseparation, and the combination of the two can realize the full size preseparation of tungsten ore.
