Abstract

Abstract

A vanadium-titanium magnetite resource has been discovered in Chaoyang, Liaoning, with the pre-selected concentrate being notable for high silicon, titanium, and vanadium content. Conducting process mineralogy research on this concentrate to explore the possibility of further silicon removal and quality enhancement is of great significance for the in-depth development and utilization of local vanadium-titanium resources. This study uses mineral processing and mineralogy research methods to identify the main minerals and their intergrowth relationships in the concentrate. The valuable minerals in the iron concentrate are mainly ilmenomagnetite, ilmenite, and a small amount of hematite. Gangue minerals are mainly silicate minerals like iron olivine and feldspar, along with a small quantity of sphene. The high vanadium and titanium content in the iron concentrate is mainly due to the presence of vanadium and titanium in ilmenomagnetite. The fine-grained gangue minerals intergrown with ilmenomagnetite lead to the high calcium and silicon content in the iron concentrate. After fine grinding and magnetic separation, the quality of the concentrate can be improved. However, due to the intimate intergrowth of fine-grained gangue minerals in ilmenomagnetite, it is difficult for conventional fine grinding and magnetic separation to fully liberate and remove the calcium and silicon elements. Therefore, even after quality improvement, the concentrate still contains 6.68% SiO₂ and 3.22% CaO.
