Baizheng company own two barite mines, which attribute deposit of high-grade pure crystal, its ore natural whiteness up to 92%, the content of BaSO4 is up to 96-99%, the density of more than 4.3,Other heavy metal impurity is very low. We can provide you with 325-5000 mesh Super-fine barium sulfate, as well ground calcium carbonate, hematite and limonite. Description: Barites is a material with environmental protecting function, it has a lot of advantages, such as a strong inertia, good stability, acid and alkali proof, moderate rigidity, high specific gravity, high whiteness, absorb in harmful radial. Field of application: Barite, or barite is one of the most abundant and widely distributed minerals throughout the world. It is mined commercially for the base element, barium, which is used as a functional filler/pigment extender in the manufacturing of products like coatings, rubber, plastics, ceramic, glass and friction materials, or used as mud for sealing oil wells during the drilling process. Barite is also used for radiation shielding and additive in heavy concrete. The other main application is for production of barium chemicals. specification high-class products First grade quality products BaSO4 % 99.0 98.0 96.0 Whiteness % 95 92-96 90-92 105°C volatile matter% 0.30 0.30 0.50 Water solvable material% 0.15 0.15 0.30 Moisture % 0.15 0.15 0.50 Fe % 0.04 0.05 0.05 Density g/cm3 4.3-4.6 Oil Absorption g/100g 9-13 PH 7-10
