The tailing of the magnetic separation from the first and second stages is combined and sent to the further process regarding receiving an Ilmenite concentrate. The magnetic separation tailing in the weak field is sent to the receiving of apatite Concentrate.
Rutile ore is a complex ore composed of a variety of minerals. Its grade is low, and the particle size is tiny. The rutile concentrate requires a titanium dioxide content of more than 87.5%. Therefore, the rutile ore process often uses gravity separation, magnetic separation, flotation, and their combined process.
