An alternative route was proposed for preparing rutile titanium dioxide (TiO2) white pigment. The process involves the digestion of titanium slag with sulfuric acid, subsequent hydrolysis of unenriched titanyl sulfate solution with ammonia, low-temperature calcination, and unseeded crystallization, producing a high-quality rutile TiO2 white pigment.

In the present study, the titanium slag, used as the raw material to prepare titanium dioxide, is manufactured by smelting ilmenite in an electric arc furnace, with anthracite as reductants (Pistorius, 2002).In this process, the titanium slag was first decomposed in NaOH system at lower temperature.
Aug 03, 2017· Also, the mineral phase of the melting-separated titanium slag is stable, and has a compact structure. There is no mature process to deal with melting-separated titanium slag at present. Only a small amount of melting-separated titanium slag is used as a raw material to produce titanium dioxide pigment in sulfate process.
Jul 25, 2018· First, let's take a look at the Titanium related products involved in the list, a total of 11 items. 2614.00.30 artificial rutile. 2614.00.60 Titanium ore and titanium concentrate, in addition to synthetic rutile. 2620.99.50 Titanium slag, titanium slag products containing more than 40% titanium. 2823.00.00 titanium dioxide
requires a pretreatment of titanium slag by fine grinding. It was found that grinding of titanium slag particles to 40 µm contributes to more complete decomposition of the anosovite with a formation of sodium titanates. It was found that during the sintering of titanium slag with soda at a mass ratio of slag:soda = 1:1.05, decomposition of the ...
The production process,capacity and product quality of main vanadium and titanium products, such as vanadium slag,vanadium pentoaide, ferrovanadium, titanium concentrate and titanium white (titania)produced at Pangang,are introduced in this paper. The new technologies for the existing process and the latest development on the recovery of vanadium and titanium are presented in detail.

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Commercial tests for fluidized-bed chlorination without sieve plate were carried out using titanium slag high or low in calcium and magnesium as main raw materials.In view of the fact that high calcium and magnesium content tends to cause agglomeration of the burden and blockage of the sieve plate which affects the normal process of chlorination,measures including gradual increase of blending ...
Titanium slag: market prices of acid dissolved titanium slag and high titanium slag dropped further in Feb. and many manufacturers stopped production during Chinese Lunar New Year and refused to ...
Preparing titanium dioxide from titania-rich slag (TiO 2 73wt%) by molten NaOH method has been developed. The effects of temperature and reaction time on the titanium conversion were investigated. The results showed that temperature had significant influence on the titanium conversion as well as the structure of the product.
Owing to smelting vanadium-titanium magnetite ore, the amount of iron entrainment in slag as droplets is far higher than that in conventional BF slag. However, the iron droplets can be easily settled by blowing air into the molten slag.
A Chinese Institute has expressed interest in technology transfer and investing in a titanium dioxide (pigment grade) manufacturing unit in Andhra Pradesh. The Institute of Process Engineering, a ...
The market trend of various products is also quite different. Among them, the titanium dioxide market is a little weak with the price lowered slightly. However, the price of titanium slag finally increased after the price of titanium tetrachloride and titanium sponge continued to increase. While the domestic titanium concentrate price is much ...
The influencing mechanism of oxygen volume percent (%VO 2) on the acid solubility of the titanium slag during the oxidization at 1273 K (1000 °C) are investigated.%VO 2 has marginal effect on the phase composition evolution, but greatly affects the microstructure evolutions during the oxidation, that is, increasing %VO 2 promotes Fe outward migration and further results in the formation of ...
Titanium-rich slag A novel process for the extraction of iron, titanium, vanadium, and chromium from high-chromium vanadium-bearing titanomagnetite concentrates is proposed.
