| Abstract: | In view of the ore properties including low TiO2 grade (10.18% TiO2), fine particle size, high content of heavy minerals and magnetic gangues, a gravity separation flowsheet by using spiral chute, consisting of one roughing and two scavenging processes, was adopted for pre-enrichment of titanium minerals, resulting in a gravity concentrate with TiO2 grade of 15.63%. Thereafter, a flotation process consisting of one stage of roughing and three stages of cleaning was introduced, resulting in the final titanium concentrate with TiO2 grade of 46.35% at an operation recovery of 69.95% and a total TiO2 recovery of 48.27%. |
