Barite is a very important non-metallic mineral raw materials with a wide range of industrial uses.
Firstly: the drilling mud weighting agent: in a number of wells and gas well drilling, the general use of drilling mud, clay, accounting for about 2.5, the proportion of water to a lower mud weight, and sometimes the mud weight can not be underground oil, gas pressurebalance, causing the blowout. In the case of underground high pressure, the need to increase the mud weight, by adding to the mud barite powder is an effective measure to increase the mud weight. Fineness do the barite used in drilling mud to reach 325 or more, such as the fineness of barite precipitation is easy enough. Drilling mud barite requirements specific gravity greater than 4.2, BaSO4 has content of not less than 95%, less than 1% of soluble salts.
Secondly，Road construction: rubber and containing about 10% of the barite asphalt mixture has been successfully used for parking, is a durable paving material. At present, the heavy road construction equipment tires has been partially filled with barite, to increase the weight, which will help fill in the compaction of the side areas.

China is the largest exporter of world barite. Barite and its annual export volume is generally 150 to 200 million tons in the 1990s. 1996 2.058 million tons of barite and the barium salt export volume, export value of $ 121 million, including 1.86 million tons barite, barium chemical products 198 000 t, the main exporting countries such as the United States, the Netherlands, Japan and South Korea. China imported barite amount is minimal, only imports a small amount of barium chemical products.
