Although the annual production of low-concentration microfine-grained ilmenite in Pan-Xi region attains over 1 million tons, it is not conducive to adopt flotation process for the subsequent titanium selection due to the microfine particle size, large volume and low concentration of this ore. For this resource, comparative experiments were conducted based on two major flowsheets, including “SLon high-intensity magnetic separation + flotation” and “desliming using new type of cyclone+flotation”. The results show that the latter process flowsheet has a lower consumption of reagents, and the obtained titanium concentrate has better indicators, with a titanium concentrate grading 47.06% TiO2 at 59.03% recovery with the yield of 20.22%.
