The recovery of pigment-grade titanium dioxide in sulfate process plants is approximately 80% (Lowenheim & Moran, 1975; Lynd & Lefond, 1983; Lynd, 1985). The chloride process is a continuous process that requires ores with a high content of titanium dioxide or concentrates such as natural or synthetic rutile.
Abstract. A rapid method for the determination of titanium in titanium dioxide pigments and related materials by inductively coupled plasma optical emission spectrometry (ICP OES) is presented. Complete decomposition of TiO 2 was achieved in a medium of (NH 4) 2 SO 4 /H 2 SO 4. Following a suitable dilution of the digest, Ti was quantitated ...

Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color ( 1 ). To be added to food, this...
Titanium dioxide is used as pigment material in the production of paints, paper, and many other products as well as a precursor material that is subsequently processed to produce titanium metal. Titanium tetrachloride is used as a precursor to titanium metal production via the Kroll process. The titanium is first processed at the …
The ores are converted to pigmentary TiO 2 by one of two main routes. In the chloride process, high TiO 2 -content ores are chlorinated in the presence of coke, a reducing agent, to give titanium tetrachloride. This is purified by distillation prior to the gas-phase oxidation.

Titanium dioxide is used by the millions of tons as a whitening or brightening pigment to make white-colored paint, but also as an additive to make white-colored food. It's added to food so much so that people eating conventional diets may be ingesting a trillion particles of titanium dioxide every day! Who cares, though?
