To develop a flowsheet for separation of high grade titaniumrutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is nonmagnetic while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.
Results of samples from the coastal area are shown in table 3. The HM content ranged from 0.4 to 7.6 wtpct. The major heavy minerals in the samples were magnetite, less than 1 to 21 lb/ton, and ilmenite, 1 to 50 lb/ton. Gold ranged from a trace to 0.0018 oz/ton, and silver from a trace to 0.0087 oz/ton.
