Introduction of Barite

Barite is the most common mineral of earthworms and its composition is barium sulfate. Produced in low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, etc., often associated with galena, sphalerite, chalcopyrite, cinnabar and so on. The barite deposits produced in Hunan, Guangxi, Qinghai and Jiangxi in China are mostly large hydrothermal single mineral veins. Barite can also be produced in sedimentary rocks and appears as tuberculosis. It is mostly found in argillaceous and sandy sedimentary rocks in sedimentary manganese deposits and shallow seas. In the residual clay cover of the weathered residual deposit, it is often knotted and massive.

The main purpose

Barite is a non-renewable resource and is one of China's export-oriented mineral products. It is widely used as a weighting agent for oil and natural gas drilling mud, and its consumption in the fields of antimony chemicals and fillers is also increasing year by year. China's barite resources are quite abundant, distributed in 21 provinces (regions) across the country, with a total reserve of 360 million tons of ore, ranking first in the world. It is medically useful for contrast agents in the digestive system.

Oil drilling Drilling oil and gas wells Rotary drilling in the circulating mud weighting agent to cool the drill bit, take away the chipped debris, lubricate the drill pipe, close the hole wall, control the oil and gas pressure, prevent the oil well from spraying, chemical production of barium carbonate, barium chloride, Various antimony compounds such as barium sulfate, zinc barium white, barium hydroxide, barium oxide, etc. These barium compounds are widely used in reagents, catalysts, sugar refining, textile, fire protection, various fireworks, synthetic rubber coagulants, plastics, insecticides. Surface quenching of chemicals and steel, phosphors, fluorescent lamps, fluxes, grease additives, etc. Glass deoxidizers, clarifiers, fluxes increase the optical stability, gloss and strength of glass, rubber, plastics, paint fillers, brighteners, weighting agents, building concrete aggregates, paving materials, heavy pipelines buried in swamp areas, instead Lead plates are used for shielding of nuclear facilities, atomic energy plants, X-ray laboratories, etc., to extend the life of the pavement.

Barite processing production process

1. The bulk barite block is first crushed by a small jaw crusher or counter-breaking to the size of the mill.

2. After the crushing, the material with the appropriate particle size is sent to the European version of T-shaped or medium-speed T-shaped grinding, LM grinding machine and other barite grinding equipment.

3. The barite pellets are ground and graded in the mill. The qualified powders are collected after passing through the classifier, and the unqualified powders are reground.

4. Packaging and storage of finished materials
