Study situation and prospects of concentration of micro-fine wolframite

The paper introduces the recovery situation and the recovery characteristics of micro-fine mineral, principles of studying concentration of micro-fine mineral and equipments for flotation of micro-fine mineral. It analyzes the causes bringing about difficulty in concentration of micro-fine mineral, and describes current situation of reagent for flotation of micro-fine wolframite and technical study in detail. In addition, after concluding main issues existing in the process of recovering micro-fine tungsten and tungsten fine mud, the paper proposes some suggestion for improving concentration process of micro-fine wolframite, and then looks into the study perspective of concentration of micro-fine wolframite.
