Pelletization performance of Panzhihua ilmenite concentrate

The influences of particle size distribution and the binder on the pelletization performance of Panzhihua ilmenite concentrate were studied in this paper. The results showed that the particle size distribution of Panzhihua ilmenite concentrate has the most important on its pelletization. The particle size distribution of ilmenite concentrate was significant changed and the specific surface area increased after grinding. The particle size of 45μm should be controlled less than 55% and 74μm no more than 74% in order to acquire a better performance of pellets. While the same performance of pellets can be obtained when the specific surface area of ilmenite concentrate was 1493cm2/g. The performance of pellets added with an organic binder is better than added bentonite. The pellet’s performance could be further improved under the mixed ratio of 1.05% bentonite and 0.45% organic binder.
