Mineral Barite introduction


Mineral Barite introduction

Barite is a sulphate mineral with a chemical formula of BaSO4 and a chemical composition of BaO65.7% and SO334.3%. Strontium and calcium are often found in the same image as Ba.

China is rich in barite resources. Proven reserves rank the highest in the world, and 22 provinces, municipalities and autonomous regions are distributed throughout the country. Guangxi is the most, followed by Hunan, Shaanxi, Guizhou, Gansu, Hubei, Fujian, Shandong and other provinces barite resources are relatively concentrated. There are more than 50 major barite deposits in China. Large deposits are mostly concentrated in the South and less in the north. Nearly half of the existing producing areas are barite associated with other minerals, some of which are difficult to concentrate and few rich. Quite a few ore deposits are located in areas with inconvenient transportation.

In China's barite ore, barium sulfate is mostly above 95%, with a small part of 90% and good quality, which can be widely used in chemical industry, oil drilling and paint industry.

Property structure of barite ore

Barite is an orthorhombic system. Each Ba2+ in the cell is linked to 7 [SO4] tetrahedron and its coordination number is 12. Crystal is often thick plate like, aggregate often grainy or crystal clusters, a few dense, clock milky and tuberculous; barite pure colorless transparent, generally mostly white, sometimes containing impurities, red, yellow, dark gray or black, glass luster, cleavage surface is pearl light, hardness 3~3.5, brittle, density 4.3~4.5g/ Cm3. Barite is chemically stable, insoluble in water and hydrochloric acid, nonmagnetic and toxic.

Function use of barite ore

Barite is the main industrial mineral material for barium and barium compounds. Barite is mainly used as a chemical for making barium, such as barium carbonate, barium chloride, lithopone, barium hydroxide and barium oxide. These barium chemicals are mainly used in white pigments, rubber fillers, medicine, pond, ceramics, optical glass, leather, and military industry. Barite is mainly used as oil and gas drilling mud. Weighting agent, and can be used as paper, paint and rubber filler. Because of its ability to absorb gamma rays, barite can be used as concrete aggregate to shield nuclear reactors and as a research and hospital building against X rays.

Barite can be used as zinc barium white and various barium compounds, as paint and other pigments, and as high-grade rubber products, oilcloth and other fillers. In addition, it can also be used as a getter and binder for extraction of metal barium, television and other vacuum tubes. Barium and other metals (aluminum, magnesium, lead, etc.) are made into alloys for bearing
