    of Fe2O3 in ilmenite and because of the process of altera­ tion of natural ilmenite. The ferric iron formed from altered ilmenite is likely to be present along the grain boundaries which are left free by the process of crushing and grinding and are separated easily by the conven­ tional methods of beneficiation

  • Current Status of Ilmenite Beneficiation Technology for

    In this study, various beneficiation processes of ilmenite for production of TiO_2 have been reviewed and compared. Most of these processes involve a combination of pyrometallurgy and hydrometallurgy.

  • Pilot-Scale Demonstration of Ilmenite Processing

    The majority of the ilmenite sample consisted of ilmenite, magnetite, lizardite, chlorite, and anorthite with lesser parts of talc and hornblende. Ten metric tons of Longnose ilmenite sample was beneficiated using gravity and magnetic separation to produce an ilmenite concentrate for hydrometallurgical testing. The beneficiation

  • Ilmenite for pigment and metal production

    Rutile is easy to process to titanium metal or TiO2 pigment by the chlorination method while ilmenite is more complicated because of its high iron content. Since the world reserves of titanium are 90% in the form of ilmenite and only 10% in the form of rutile, the treatment of ilmenite is evidently an important question in metallurgy [1,2].
