| Abstract: |
| Process mineralogy and beneficiation of the titanium-contained iron tailings from Panzhihua was investigated in this paper. The results showed that the grades of titanium and iron in the ore were 6.25% and 11.84%, respectively. The titanium phase was mainly in the form of ilmenite, which occupied 59.38% in the total titanium. Additionally, the titanium existed in the sphene and silicate minerals as much as 29.39%. The distribution size of ilmenite aggregate was 0.016~0.032 mm. Thus, the ore belonged to a low grade and fine-grained ilmenite. The results of exploratory separation tests confirmed that the TiO2 grade of the high intensity magnetic separation (HIMS) concentrate was 11.36%, and the recovery rate was 76.54% under a grinding fineness of -0.048 μm accounting for 85% and a magnetic field intensity of 1.2 T. After an open-circuit flotation test of HIMS concentrates via "one-time roughing, one-time scavenging and three-times cleaning", 46.56% TiO2 concentrate and operating recovery rate of 42.71% were obtained. The combined process of HIMS and flotation provided an easy access to recover the ilmenite for this tailing. This paper provided some guidance for the secondary utilization of similar titanium-contained iron tailings. |
