| Abstract: |
| Magnesium-bearing silicate minerals such as serpentine, chlorite and talc often coexist with valuable metal minerals, which are difficult to be suppressed in the process of flotation separation, resulting in excessive magnesium content in the concentrate, which has a badly impact on smelting. Therefore, it is urgent issue that how to achieve efficient beneficiation and magnesium reduction for the industry. The research development of magnesium reduction was summarized through investment of process and inhabiting mechanism of depressant of magnesium reduction, and the structure and surface characteristics of serpentine, chlorite and talc were concluded respectively in this paper, which demonstrates the reasons that magnesium-bearing gangues are difficult to separate and inhabit from various aspects further more. At the same time, the development trend of magnesium reduction technology by mineral processing is prospected to provide some reference for other similar mine. |
