Abstract
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.

The development of titanium industry requires large number of high quality titanium ore
Titania slag prepared by smelting of ilmenite in an electric arc furnace (EAF) can be served as a superior quality raw materials containing titanium to the pigment or other titanium products industrial processes[1]

Summary
The development of titanium industry requires large number of high quality titanium ore. Titania slag prepared by smelting of ilmenite in an electric arc furnace (EAF) can be served as a superior quality raw materials containing titanium to the pigment or other titanium products industrial processes[1]. Particle size of Panzhihua ilmenite concentrate has become more and more fine. Ren[4] reported on the effect of grinding time, binder and drying temperature on pelleting of Panzhihua fine ilmenite concentrate. They did not consider the effect of particle size distribution. There are few studies on pelletization performance of Panzhihua ilmenite concentrate in the literature The purpose of this present investigation was to study the effect of particle size distribution and binder on the pelletizing of ilmenite concentrate, while, obtaining a better parameter to improvement pelletization performance of Panzhihua ilmenite concentrate
