Research of the Occurrence State of the Main Impurities in Panxi Ilmenite

Through the research of the mineral structure of vanadium-titanium magnetite and the mineral process technology of titanium concentrate in Panxi area,the distribution of the main elements and the state of the impurity elements were concluded by deeply profiling of the titanium concentrate using XRD and SEM.Panxi titanium concentrate based on the lattice of metatitanic acid iron（FeO·TiO₂）,is a solid solution with Mg and Mn,etc.The main impurity elements,such as Si,Ca,Mg,Al,Fe and Ti,etc.,are dissolved as one or more types of oxide,in silicate which is associated with ilmenite.According to different purposes,the deeply graining and adjusting the parameters of separation technology for ilmenite concentrate were put forward to produce high quality ilmenite concentrate for realizing high value-added utilization.
