Synthetic Rutile Market: Revenue to Witness Steady Growth ...
Rutile is primarily composed of titanium dioxide. Synthetic rutile is produced from naturally-occurring ilmenite, which is a complex oxide of iron. Synthetic rutile is used as a byproduct of titanium dioxide. Synthetic rutile can be made of different colors by the doping method.
SYNTHETIC RUTILE FROM ILMENITE - Entrepreneur India
Synthetic rutile (TiO2) is manufactured through the upgrading of ilmenite ore to remove impurities (mostly iron) and yield a feedstock for production of titanium tetrachloride through the chloride process. The stone composition of synthetic rutile is similar to that of natural rutile, but differs in physical form.

Oxidative conversion of Fe2+ to Fe3+ facilitates the iron exchange to the resin, resulting in an iron-free solution of titanium oxychloride (TiOCl2). This can be directly used to produce synthetic...
Synthetic Gemstone Guide
Synthetic rutile can be made by the Verneuil process in a variety of colors, including brown, yellow, red, and blue. Completely colorless stones cannot, however, be produced and always have a tinge of yellow. The colored varieties were seldom seen in the gem trade. Rutile is too soft to be useful as a gemstone (hardness 6-6.5 on the Mohs scale).
Direct reduction of synthetic rutile using the FFC process ...
Jan 22, 2016 · Alternatively, TiO 2 is obtained from the more abundant iron-containing ore, ilmenite (FeTiO 3). Rutile created from ilmenite is known as synthetic rutile. A range of methods exist to produce synthetic rutile from ilmenite, such as the Becher, Benelite, Laporte, and Murso processes [ 17 ].

Titanium processing - Extraction and refining | Britannica
Only natural rutile meets this requirement, but ilmenite can be upgraded through combinations of pyrometallurgical and hydrometallurgical techniques to produce a synthetic rutile of 90 to 93 percent TiO 2. In addition, titaniferous magnetite ores can be smelted to produce pig iron and titanium-rich slags.
Ilmenite for pigment and metal production
The hydrometallurgical route was developed in 1960s and involved leaching of iron from ilmenite and obtaining a residue rich in titanium (90–95% TiO 2) known as “synthetic rutile”. In one case, the Altair
