Titanium sand, a sand containing titanium. Yunnan Province is rich in titanium sand ore resources, most of which are secondary inland sand ore, mainly distributed in Fumin, Luquan, Wuding other areas near Kunming. The titanium sand ore in this area is easy to mine beneficiated, titanium concentrate with good quality can be obtained through simple beneficiation. Magnesia carbon brick

The main useful components of the ore in this area are titanium iron, the associated components are aluminum magnesium, with few other components. Titanium is mainly present in the form of ilmenite, with a small amount of brookite; iron is also present in the form of vanadium-titanium magnetite in addition to ilmenite. In the production, ilmenite Vanadium titanium magnetite. The particle size analysis shows that the grade of the medium-sized grain group the grade of the fine-grained group, but the fine-grained level accounts for a considerable proportion. As titanium ore beneficiation is mainly based on gravity separation, the fine-grained grade is easily lost under the action of gravity water flow, which affects the recovery rate.
