Moreover, Drzymala (Drzymala and Euszczkiewicz, 1985) investigated the effect of gravity separation of ilmenite and spinel. Due to the large density difference between spinel and ilmenite, gravity separation can easily separate the two minerals, ultimately producing a high-quality titanium concentrate with a TiO 2 grade of 45 %.

Magnetic Separation

The separation is between economic ore constituents, noneconomic contaminants and gangue. Magnetite and ilmenite can be separated from its nonmagnetic RFM of host rock as valuable product or as contaminants. The technique is widely used in beneficiation of beach sand. All minerals will have one of the three magnetic properties.
