Do you want high-quality mines? Try sodium hexametaphosphate
Due to the increasingly scarce mineral resources, mineral mining increasingly uses lean and complex ore, so the amount of ore that needs to be processed is increasing. Beneficiation can improve the quality of mineral raw materials, reduce transportation costs, alleviate further processing difficulties, reduce processing costs, and realize the comprehensive utilization of mineral raw materials. Sodium hexametaphosphate is a commonly used regulator and inhibitor in mineral flotation.
The type and amount of flotation agent vary with the nature of the ore and the flotation conditions and process characteristics, and can also be changed according to the changes in the above-mentioned various conditions during the production practice.
The role of sodium hexametaphosphate in the regulator can be divided into five categories: (1) pH regulator (2) Activator (3) Inhibitors (4) Flocculant (5) Dispersant
Application in mineral processing and oilfield industry Sodium hexametaphosphate is commonly used in flotation, as well as carbonate minerals such as calcite and limestone. It is mainly used to suppress quartz and silicate minerals. The mineral processing mechanism of sodium hexametaphosphate is mainly:
Sodium hexametaphosphate can be used as an inhibitor in flotation operations to inhibit minerals containing these ions. It is an inhibitor of apatite, calcite, barite, carbonaceous shale and argillaceous gangue. This is because sodium hexametaphosphate can form complexes with Ca2+, Mg2+ and other multivalent metal ions. When flotation of pyrochlore containing niobium, tantalum, thorium and zirconium containing zirconium, sodium hexametaphosphate can be used to inhibit Gangue minerals such as feldspar, nepheline and kaolin.
In the flotation of albite, zircon nepheline, pyrochlore and kaolinite, sodium hexametaphosphate can reduce sodium oleate without selectivity according to the tracer atomic test, and can react with multivalent metal ions of mineral profile.
