Separation of Barite

Source:

1.The meaning of barite

Barite is the most common mineral of barium and its composition is barium sulfate. Produced in the low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, and often with Galena, sphalerite, chalcopyrite, cinnabar and other symbiotic.

Chemical composition: bao:65.7%,so3:34.3%. The components include SR, PB and CA-like substitutes.

2.The use of barite,

Barite is a very important nonmetal mineral material, which has a wide range of industrial uses. Barite belongs to non-renewable Resources, is one of China's export advantage minerals, widely used in oil, natural gas drilling slurry of the aggravating agent, in barium chemical, filler and other fields of consumption is also increasing year in. China barite resources are abundant, distributed in the country 21 provinces (districts), the total reserves of ore 360 million tons, ranked 1th in the world. It can be used in medical treatment of contrast agents in the digestive system.

Secondly, barite is also widely used in drilling mud aggravating agent, zinc barium white pigment, all kinds of barium compound, filler industrial barite, cement industry with mineralized agent, road construction and so on.

3.The distribution of barite, The barite deposits in China are classified into layered, layered, vein-shaped, reconstructed veins and stacked type of four types of deposits. Layered barite deposits are controlled by strata and lithofacies, and most of the vein barite deposits are related to a certain period of strata in most regions.

In some areas, layered barite deposits and vein-shaped barite deposits are produced in the same age strata. China's abundant barite resources, the country's 26 provinces, municipalities and autonomous regions are distributed, mainly concentrated in the south, Guizhou province accounted for the total reserves of One-third, Hunan, Guangxi, respectively, the second and third in the country, the Chinese barite not only large reserves, but also high grade, baso4>92.8%. Rich ore reserves accounted for 99.4% of the total amount of the national bonanza, large and medium-sized mineral reserves accounted for 88.4% of the total, as at the end of 95, China has proven barite reserves of 460 million tons.

4.The sorting of barite, With the exhaustion of high quality and single type barite ore, most of our country is low in quality barite, which is closely associated with other metal ore and nonmetal ore, and directly affects its utilization value in industry. Barite has different requirements for the purity, whiteness and impurity content of barite.

Ore color sorter, as a new automatic equipment for mineral selection, is also gradually applied to the separation of barite by color, and has obtained more superior results than the original purification method.

In short, the introduction of ore color sorter, the continuous development of mining production technology, the development of barite in China is very important. It can not only solve the dilemma of domestic barite development, but also opened a new chapter of its rapid development. Domestic mining development is imminent, the urgent need to apply advanced mining equipment, the introduction of advanced ore color separator, reduce the cost of imports to reduce the domestic mining industry crackdown, relying on technology to seek development.
