TITANIUM TETRACHLORIDE PRODUCTION BY THE …

 · 3.2 Chloride-Ilmenite Process In the chloride-ilmenite process, ilmenite, which, even at high grade, has a substantially lower TiO 2 content (approximately 65%) than rutile, is converted to TiCl 4. The ilmenite ore used in the process contains a much larger amount of iron than the other ores (i.e., rutile or high-grade ilmenite) used to produce ...

Chloridization beneficiation of ilmenite | SpringerLink

Chloridization is a potential method of beneficiating ilmenite. Studies on beneficiation of ilmenite were carried out by using titanium chloride as the chloridizing agent in a laboratory scale fluidized bed reactor. Experiments were conducted on 1, 10, and 36 grams per batch scale, and the effect of the various rate determining steps on conversion was studied. Treated particles of ilmenite ...

Ilmenite Beneficiation by Roasting and Magnetic Separation

A new crude ilmenite beneficiation process was recently proposed that allowed for the preparation of a smelter grade ilmenite from ilmenite with elevated chromium content. Magnetising roasting was not utilised in the process. As part of this circuit an ilmenite low susceptible reject stream was produced that had a low magnetic susceptibility.
