Research on Gravity Separation of Anosovite from Ti-bearing Slag

In this paper,the method of gravity separation by spiral chute was used to separate the anosovite phase from titanium-bearing slag,thereby realizing the selective separation of titanium components and laying the foundation for comprehensive utilization of the titanium resources.The titanium-bearing slag was ground to different particle size limits,and the monomer dissociation degree of anosovite phase was determined.According to the statistical results,when the upper limit of the particle size of titanium-bearing slag was 74 μm and 50 μm,the monomer disassociation degree of anosovite phase was relatively high,which was 77.76% and 82.18% respectively. A set of optimal gravity-separation experimental parameters was obtained through gravity separation.When the position of the wedge-shaped block was controlled at 3 cm from the inner edge of the chute,the number of chute laps was 5 and the ore concentration was determined at 35%,consequently,the grade of TiO₂ in the concentrate reached 67. 19%,the recovery rate of TiO₂ was 61.62% and the recovery rate of anosovite was 68.74%.
