Mineral Composition and Distributions of Fe and Ti in Low-grade Titanic Ore from Linyi

The distributions of Fe and Ti, and mineral composition of low-grad titanic ore in Linyi, Shandong, were investigated by a mineral liberation analyzer(MLA). The results show that TFe and Ti O2 contents are 14.25% and 6.68%, respectively. Magnetite, ilmenite and titanite account for 2.60%, 5.40% and 8.27%, respectively. Hornblende is the major gangue mineral, and next anorthose. The content of magnetic Fe is only 1.88%, which accounts for 13.21% in total Fe. Ti distributed in ilmenite accounts for 40.69%, and the other 44.14% is distributed in titanite. When ilmenite and titanite were used as the target minerals in mineral processing, the theoretical Ti O2 grade, recovery rate of titanium and yield of titanium concentrate would be 41.45%, 84.83 and 13.67%, respectively.
