the production of titanium dioxide using low grade

Titanium Dioxide - Production, Properties and Applications January 2014 In book: Titanium Dioxide: Chemical Properties, Applications and Environmental Effects (pp.75)

For the production of high-grade titanium dioxide (TiO 2) directly from titanium ore (Ti ore), a fundamental study on the development of a novel carbo-selective-chlorination method using titanium tetrachloride (TiCl 4) as a chlorinating agent was carried out. In order to selectively remove iron directly from low-grade Ti ore (mainly FeTiO

Dec 01, 2012· Highlights Anti-caking in the process of produce titanium dioxide without introducing additives has been achieved successfully. Powder shaped intermediate product was obtained through new method. BET surface area and apparent density were used to characterize the extent of caking. Silicate phase in the low-grade titanium slag was reacted with molten NaOH ahead of …

TiO 2 is currently produced using either Chloride process or Sulfate process, which have environmental challenges. An innovative environmentally friendly hydrometallurgical process has been developed by Process Research Ortech Inc. This process is capable of treating a wide variety of ores including low-grade ores and ores containing Mg, V, or Cr.

The grade of titanium dioxide being too low, resulting in uneconomic, large effluent or by-product generation rates, or The presence of contaminants that cannot be handled by commercial processes. Specific examples of such resources include: Titanium bearing slag from steel production plants using titaniferous magnetite as feedstock (i.e.

Dec 01, 2012· The method, which involves the two-step reaction of low-grade titanium slag with molten NaOH without the introduction of additives, can significantly reduce the extent of caking. The NaOH and low-grade titanium slag mixture was first reacted at 350 °C for 60 min. The temperature was then increased to 550 °C in 40 min.

In order to selectively remove iron directly from low-grade Ti ore (mainly FeTiO3), Ti ore and carbon powder were set in a gas-tight ...

Mar 15, 2010· Mar 15, 2010· Titanium Dioxide (TiO2) Production and Manufacturing Process. TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores.

Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide's excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is ...

The caking and adhesion of intermediate product on reactor surfaces during TiO2 production via the NaOH molten salt method are a serious problem. The consolidation of intermediate product can lead to low heat transfer efficiency and low titanium fractional conversion. Furthermore, frequent cleaning is generally required. An anti-caking method that can be applied during low-grade titanium slag ...

Highlights Anti-caking in the process of produce titanium dioxide without introducing additives has been achieved successfully. Powder shaped intermediate product was obtained through new method.

C = Indoor use 2 The titanium dioxide content and density of the pigments de-pend on the type and quantity of the treatment substances used to improve the application properties. Pure rutile has a density of 4.2 g/cm3, while pure anatase has a density of 3.8 g/cm3. 3 The relative scattering power is the decisive parameter for the
