Abstract

Abstract

The floating titanium concentrate grade of a concentrator in Panxi area is 46.84%, among which gangue minerals SiO₂ and CaO are not conducive to the subsequent chlorination process of titanium dioxide. Adding inhibitors to acidified sodium silicate, sulfuric acid, sodium silicate, sodium fluorosilicate and lignin can effectively inhibit gangue minerals from floating and improve the grade of titanium concentrate, among which sulfuric acid and lignin show the best effect, and sulfuric acid is determined to be the quality improvement flotation inhibitor. The effects of stirring time, sulfuric acid dosage and collector dosage on the final grade and recovery of titanium concentrate were investigated by a single flotation process. The optimal flotation conditions were determined to be stirring time of 10 min, sulfuric acid dosage of 2000 g/t and MOH dosage of 2000 g/t. Under the optimal flotation conditions, the grade of titanium concentrate can be increased from 46.84% to 50.04%, the recovery rate of titanium concentrate is 41.93%, and the CaO+SiO₂≤1.5%, which meets the quality improvement requirements.
