Manufacturing Process

Titanium dioxide is extracted from the earth "from titani-ferrous minerals such as illminites, found in the dark sand beaches in Australia, India, South Africa and the USA" (Ellis, 2008). Once extracted, the titanium dioxide is mixed in with the other components and packaged in a small bottle that includes a brush that is attached to the lid of the bottle.

Titanium dioxide pigment production process

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. The chloride route requires the construction of a chloralkali unit and a higher automation control system. There is more solid waste produced from the chloride route.

Titanium Dioxide (TiO2) Production and Manufacturing Process

 · 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 | S-GROUP

The nature does not provide titanium dioxide in a usable form. It has to be mined carefully in one of its pure forms and refined into fine equal particles. Chloride and sulphate processes are used to achieve that. KRONOS has been granted original patents for the sulphate process and is producing the titanium-dioxide pigments by using this procedure continuously since 1916.

Titanium Dioxide Production Process | Quarrying & Aggregates

The process flow is: sulfuric acid decomposes titanium ore into TiOSO4. After purification and concentration, the titanium solution is hydrolyzed into TiO2•H2O. The hydrolyzed product is washed, filtered, and calcined before surface treatment, and separation and impurity removal work should be carried out in a timely manner.

Manufacturing process of Titanium Dioxide | Valco Group

Manufacture takes place by either the sulfate process or the chloride process and the main raw materials include ilmenite (FeO/TiO2), naturally occurring rutile, or titanium slag. In essence the process converts the impure TiO2 feedstock into an easy to purify intermediate, separates out the impurities then converts back to pure TiO2 (see figure 1).
