Barite is a non-metallic mineral product with barium sulfate as the main component. It is the most common mineral of barium. It is produced in low-temperature hydrothermal veins and often coexists with galena, sphalerite, chalcopyrite, etc. It has the advantages of high density, being insoluble in water, being non-toxic, being easy to absorb radiation, and having good filling properties. It is widely used in petrochemicals, building materials, metallurgy, textiles, electronics, building materials, medicine, and other industries.
The proportion of barite commercial-grade rich ores with grades higher than 90% has declined. Salts and carbonate minerals coexist and must be beneficiated before use. Under normal circumstances, the grade or specific gravity of native barite ores cannot meet industrial production requirements due to the presence of impurities such as other gangues. Therefore, the specific gravity or grade must be increased through a barite beneficiation line to meet industrial requirements before selling. Impurities and undesirable components can be removed from barite ore through crushing, washing, gravity, magnetic, and flotation separation processes, thereby obtaining higher purity.
