Outline
In order to comprehensively recover titanium resources and iron resources from a low-grade ilmenite ore, an experimental study was performed for the ore by a process of low intensity magnetic separation (LIMS) followed by regrinding and re-concentration to recover Ti and Fe therein. The results show that LIMS with ore at a grinding fineness of－0.074 mm 84.78% can yield an iron concentrate grading 62.82% TFe and 3.62% TiO2 with iron recovery of 51.32%, presenting a good recovery of magnetic iron; the obtained LIMS concentrate is subjected to high-intensity magnetic separation (HIMS) consisting of one roughing and one cleaning, followed by gravity separation with a shaking table, resulting in the obtained Ti concentrate grading 40.81% TiO2 at 18.47% recovery. It is shown that both Fe and Ti therein can be comprehensively recovered.
