Study on the Occurrence State of Titanium in a Titanium-containing Ore

In order to study whether a titanium-containing ore has comprehensive utilization value, its material composition, target mineral dissemination characteristics and occurrence state of valuable elements were systematically studied by means of optical microscope, X-ray diffractometer, scanning electron microscope, mineral automatic analyzer and electron probe.The results show that the ore is a diorite containing iron and titanium. The grade of TiO₂ in the ore is 2.27% and the grade of TFe is 11.36%. The iron grade in the ore is low and does not reach the lowest industrial grade of iron ore. TiO₂ in ore mainly exists in ilmenite and ilmenite amphibole, and the distribution rates are 40.02% and 44.75% respectively, accounting for 84.79% of the total distribution rate. A small amount of TiO₂ is distributed in titanite, rutile and magnetite ( hematite ), with distribution rates of 7.93%, 5.67 % and 1.59%, respectively. The mineral content of ilmenite and rutile is only 1.86% and 0.13%. The content of rutile in the ore is very low, which is mostly associated with titanite and ilmenite, and the particle size is fine. Rutile contains calcium, iron, silicon and other impurity elements, which will directly affect the grade and recovery rate of rutile concentrate. The useful minerals in the ore can be effectively recovered by using the stage grinding stage selection process and the combined process of gravity separation, magnetic separation and flotation.
