Titamium Dioxide Rutile (Anatase)

Production method

It is mostly from strip mining. The selection of ore for the primary deposit of Titanium can be divided into three stages including pre-selection (usual through magnetic separation and gravity separation), iron selection (using magnetic separation) and Titanium selection (gravity separation, magnetic separation, electrostatic separation and flotation); The ore selection of Ti-Zr sand mineral (mainly include beach placer, followed by inland placer) mineral processing can be divided into two steps including roughing selection and featured. In 1995, the mining department in Zhengzhou Institute of comprehensive utilization had applied magnetic separation-gravity selection-acid leaching process for ore selection on the large-scale rutile ore in Xixia of Henan Province and had already passed the trial production with various kinds of indicators reaching the domestic leading level.

General description

Titanium dioxide is naturally presented in titanium ore and rutile titanium. Its molecular structure makes it contain high luminance and covering property. But it must be subject to first extraction and purification. 60 years ago, the DuPont Company had developed the chlorination process as the production technology of titanium dioxide. Because of its relative old sulfuric acid process, it is capable of manufacturing high-quality paint products while reducing environmental emissions and energy consumption and therefore has become the preferred technique in the world. Titanium dioxide (or TiO2) is the most widely used white pigment in the field of industry, being used in architecture, industry and automotive coatings; furniture, electrical appliances, plastic tape and plastic box-purpose plastic; high-grade magazines, publicity pictures and paper for attached film as well as specialty product such as ink, rubber, leather and elastomers.

Definition

Rutile: A naturally occurring reddish-brown form of titanium(IV) oxide, TiO4. It is an ore of titanium and is also used in making ceramics. Some clear varieties of rutile are used as a semiprecious gemstone.
