POST-TREATMENT OF ILMENITE ORE SUBJECTED TO SELECTIVE CHLORINATION TREATMENT ABSTRACT OF THE DISCLOSURE Process for post-treating a chlorinated ilmenite ore which has undergone a selective chlorination treatment in the presence of a solid carbonaceous material, which comprises subjecting the chlorinated ilmenite ore to a magnetic separation in a high magnetic field to separate it into a magnetic portion and non- magnetic portion, subjecting the residual of the solid carbon- aceous material concentrated in the non-magnetic portion to flotation, using a frothing agent such as methylisobutylcarbinol and a collector for a sulfide ore such as xanthate, Aerofloat or the like, and washing a gangue value partially liberated from the ilmenite ore with water or suspending it in water in said flotation to separate these materials respectively thereby to produce an artificial rutile with a TiO2 content of at least 95% as a final product.
