ilmenite and chrome separation

US5595347A - Process for separating ilmenite - Google Patents

Annealing (17) of the roasted product improves the resultant magnetic susceptibility. Ilmenites having inclusions or selvedges of silicate minerals are further improved by employing a grinding step after magnetic separation prior to slagging or use as synthetic rutile feedstock. The roasting stage potentiates the ilmenite for...

Selective sulfidising roasting for the removal of chrome spinel ...

Existing magnetising roast processes currently used in the industry do not allow a clean separation of the chrome-rich spinets from the ilmenite due to overlapping physical properties. It has been suggested that selective sulfidation of chrome-rich spinels could be a potential route for chromia separation from ilmenite.
