PROCESS TO OBTAIN ANATHASE MECHANICAL CONCENTRATES

摘要

Process of obtaining an anathase concentrate from an anathase ore comprehends the reduction of the anathase ore to dimensions inferior to 125 mm; disaggregation in water; classification of the suspension and elimination of slimes and silicates; grinding of the deslimed fraction and low intensity magnetic separation; grinding of the non-magnetic fraction to a value inferior to 32 mesh; calcining and slight reduction to turn the limonite and the hematite into magnetite and elimination of the magnetite in low intensity magnetic separator; and electrostatic separation of the non-magnetic fraction to obtain, as conductor, a final product which is rich in anathase and has a low grade of impurities.
