Magnetic separation is used to separate the magnetic minerals (ilmenite and monazite) from the non-magnetic minerals (rutile and zircon). This removes oxygen from the ore and produces metallic iron within the ilmenite. Ilmenite grains are converted to porous synthetic rutile grains with metallic iron and other impurity inclusions.
