Abstract：In order to obtain the basic process mineralogy data of a vanadium-titanium magnetite ore in Panxi and provide basic process mineralogy data support for the development and utilization of the ore deposit (including mineral composition, content, element distribution, theoretical recovery rate, etc), the advanced mineral identification and characterization system (AMICS) was adopted to study the vanadium-titanium magnetite in Panxi. The massive vanadium-titanium magnetite from the mining area was treated by crushing, grinding, and dividing in laboratory to obtain the powder samples. To reduce the experimental error caused by the difference in particle size, the powder samples were sieved into 8 grades, and then made into light sheets. The classified vanadium-titanium magnetite sample were studied by AMICS after metal spraying. The process mineralogy characteristics such as mineral composition and content of the ore, the occurrence state of key elements, and the dissociation of the ore minerals were identified. The results showed that the ore minerals in vanadium-titanium magnetite in a mining area in Panxi were mainly composed of titanomagnetite and ilmenite, and the gangue minerals were mainly silicate minerals such as diopside, amphibole and olivine. The element of Fe in ore were mainly present in titanomagnetite and ilmenite, with a distribution rate of 71.85% and 7.80%, respectively. Moreover, 19.46% of Fe element was distributed in silicate minerals, which was hardly recycled.
