Purification, application and current market trend of ...

The electrostatic separation method is the exclusive choice in some specific situations, for example, the case of rutile (TiO 2) and ilmenite (FeTiO 3) deposits (see Table 5). These deposits generally contain minerals of similar specific gravities and surface properties. Hence, the flotation process is usually inappropriate for concentration.
