Detailed introduction
Barite ore is a non-metallic mineral product mainly composed of barium sulfate (BaSO ₄). Pure barite appears white and glossy, and is often gray, light red, light yellow, etc. due to the influence of impurities and impurities. Its chemical composition includes about 65.7% BaO and about 34.3% SO æ, sometimes with Sr, Pb, and Ca isomorphic substitutes in the composition. Barite has stable chemical properties, is insoluble in water and hydrochloric acid, has no magnetism and toxicity. Its crystals belong to the orthogonal (rhombic) crystal system, often in the form of thick plate-like or columnar crystals, mostly dense block like or plate-like, granular aggregates. When pure, it is colorless and transparent. When containing impurities, it is dyed into various colors, with white stripes and a glass luster. It is transparent to semi transparent, with a Mohs hardness of 3-3.5 and a specific gravity of 4.0-4.6.
In industry, barite is widely used as a filler in industries such as rubber, plastics, and paper, which can increase the weight, hardness, and stability of products. In the medical field, pure barite can be used as an X-ray contrast agent for X-ray examinations and CT scans, helping doctors better diagnose diseases. In addition, barite is also used as a weighting agent for oil and gas drilling mud to increase wellbore stability, control well pressure, and prevent blowout.
Barite resources are widely distributed around the world, mainly concentrated in China, the United States, India, Iran, Kazakhstan, Pakistan, Morocco, Türkiye, Mexico, Russia and other countries. China's barite resources are also quite abundant, with high-quality and rich minerals mainly concentrated in Guizhou and Guangxi.
In terms of mining, the mining of barite can be roughly divided into two methods: underground mining and open-pit mining. Underground mining is suitable for mineral areas with narrow veins and large dip angles of ore layers, while open-pit mining is suitable for mineral areas with larger veins and thicker ore layers.
Overall, barite ore is a multifunctional and versatile mineral resource with extensive applications in multiple fields. If you need more information about barite ore, it is recommended to consult relevant literature or consult geological and mineral experts.
