Titanium dioxide - Wikipedia

The production method depends on the feedstock. The most common mineral source is ilmenite. The abundant rutile mineral sand can also be purified with the chloride processor other processes. Ilmenite is converted into pigment grade titanium dioxide via either the sulfate process or the chloride process. Both sulfate and chloride processes produce the titanium dioxide pigment in the rutile crystal form, but the Sulfate Process can be adjusted to produce the anatase form. Anatase, being softer, is used in fiber an

The current rate of industrial production of titanium dioxide, from natural ilmenite, is around 6500 kT per annum. The two main processes used, namely, sulfate and chloride processes, require concentrated corrosive acids and drastic conditions, such as 1000 °C, in open processes, thus contributing to considerable costs and environmental pollution. To reduce the cost and impact to the ...

Ilmenite - chemeurope

Ilmenite is converted into titanium dioxide via the sulphate process. Sulphate process plants must utilise low-vanadium ilmenite, as vanadium is a penalty element. Titanium dioxide pigment can also be produced from higher titanium feedstocks such as rutile and leucoxene via a chloride acid process.

Ilmenite - Sangam

(The technology for processing Ilmenite into Titanium dioxide remains almost exclusively with two Multi-national corporations Dupont and Kermaggees.) A Titanium dioxide plant would require a large supply of fresh water. The Yan Oya river which flows between Pumoddai and Thiriyai was considered an ideal source of supply.

Titanium Dioxide Production by Hydrochloric Acid Leaching ...

conventional process, a large fraction of ilmenite is being rejected un-dissolved and the co-dissolved other transition metal ions may be co-precipitated with titanium, which may seriously discolor the white pigment color of titanium dioxide. In our laboratory, a few processes have also been tested for the recovery of titanium dioxide.

The ilmenite is then transported to our Sorel-Tracy metallurgic complex, just over an hour from Montreal, for processing into iron and titanium. The large complex – as big as 100 American football fields – also houses a technology centre.

Ilmenite for pigment and metal production

Rutile is easy to process to titanium metal or TiO2 pigment by the chlorination method while ilmenite is more complicated because of its high iron content. Since the world reserves of titanium are 90% in the form of ilmenite and only 10% in the form of rutile, the treatment of ilmenite is evidently an important question in metallurgy [1,2].
