100,000 tons of hydrochloric acid extraction method titanium white project trial production

The first production line with an annual output of 100,000 tons of hydrochloric acid extraction method titanium white and 100,000 tons of iron oxide began trial production on December 12. Kuncai Science and Technology Jiangyin Industrial Park is an important part of Jiangyin chemical new materials zone, covers an area of 1158 acres, the total planning for an annual output of 500,000 tons of titanium dioxide, 500,000 tons of iron oxide and functional titanium dioxide, becoming China's largest hydrochloric acid extraction method titanium dioxide, iron oxide research and development, production, sales integration of enterprises, the second annual output of 100,000 tons of titanium white and 100,000 tons of iron oxide is expected to be put into production after the Spring Festival next year, all expected to be put into production after the Spring Festival next year.
China introduced the first generation of titanium dioxide technology from abroad in the 1970s, nearly 50 years ago, the introduction of the second generation of chlorination production of gold-redstone titanium dioxide powder more than 10 years, key product technology compared with overseas still exists a large difference, in the middle and high-end areas of the application is still dependent on imports . Compared with sulphuric acid and chlorination, hydrochloric acid titanium dioxide has a unique advantage. The by-product of the process in the preparation of titanium dioxide FeCl2/FeCl3 can be converted into iron oxide reuse through hot water hydrolyzing, while the hydrochloric acid generated can be returned to the main line of titanium dioxide production, which avoids the environmental pressure caused by iron sulfate, a by-product of the production process of sulphuric acid. Hydrochloric acid can be produced using ordinary titanium iron ore as raw material, which has some advantages in raw material selection compared with chlorination method, which requires higher raw materials.
