Titanium Raw Materials Special Implementation
May 25, 2017

Impurities in titanium-containing materials, in particular, are not only radioactive nuclides such as uranium and thorium but also their radionuclide bodies. Titanium Raw Materials The invention also relates to a special implementation scheme for removing uranium and thorium from a wind erosion or "altered" ilmenite and a product produced by the ilmenite.

Ilmenite (FeTiO3) and rutile (TIO2) are the main mineral materials with important industrial Titanium Raw Materials value in the production of titanium and Titania. Although ilmenite and rutile invariably coexist in nature as "ore" or "heavy minerals" (as well as zircon (ZrSiO4) and solitary stones (CE, la, th) PO4, ilmenite is usually the richest. The natural weathering of ilmenite leads to partial oxidation of iron, iron was originally in the iron ore in the Iron State ($literal) exist, after the oxidation of iron ions (+), in order to maintain the neutral, Titanium Raw Materials some of the oxidized iron is certainly removed from the lattice of ilmenite, resulting in a higher titanium content (iron content is lower) porous structure. The wind-blown material is known as "altered" ilmenite, and the TiO2 content is likely to exceed 60%, compared to the chemical calculation (52 7) ilmenite. As the ilmenite wind erosion or alteration, impurities such as aluminum silicate (clay) are often dispersed into the pore structure of small particles, Titanium Raw Materials which exist in the pores of altered ilmenite. In this process, it appears that uranium and thorium can also enter the pores of the ilmenite.

Most of the world's mined titanium ores are used to produce titanium dioxide pigments for use in paints and paper industries. The traditional production method of pigment grade TiO2 is through the reaction of ilmenite and concentrated sulfuric acid to produce TiO2 pigments-the so-called sulfate route. However, Titanium Raw Materials because of the large amount of acidic waste produced, this approach is becoming increasingly unpopular on environmental grounds. Another method-the so-called chloride route-consists of four chlorinated titanium that reacts with chlorine to produce volatile TiO2. Unlike the sulfate route, the chloride route can handle raw materials (such as rutile) with high TiO2 content and low iron and other impurity content.

Due to the chloride route, which has hardly environmental problems becomes thus the optimal method of the TiO2 pigment production. On the other hand, the sulfate route can only produce TiO2 pigments, while the chloride route can produce both titanium and TiO2 pigments. Titanium Raw Materials The supply of natural rutile cannot adequately meet the needs of the world's chloride route approach. As a result, it is increasingly necessary to convert a large number of ilmenite (TiO2 $number) into synthetic rutile (with TiO2 more than 90%). In order to raise ilmenite to artificial rutile, many different methods have been developed, the most widely used and industrial value is the Becher method
