The gabbro-type apatite-containing ilmenite ore was tested by flotation-gravity separation to obtain two concentrates of ilmenite and apatite. Due to the limited resources of high-titanium minerals, various methods of producing rutile from ilmenite have been studied. For example, choose the chlorination method and the reduction rust method.

Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.
