Abstract: The process mineralogy of vanadium-titanium magnetite from Panzhihua, Chengde and Chaoyang is studied, and the value of the ore is calculated according to the spot price of iron concentrate, titanium concentrate and the theoretical mineral processing index. The results show that the grade of magnetic iron is 13.26%, 12.84% and 1.15%, the grade of TiO2 is 10.98%, 4.53% and 2.02%, and the grade of V2O5 is 0.22%, 0.23% and 0.055%, respectively, in vanadium- titanomagnetite from Panzhihua, Chengde and Chaoyang. The mineral contents and mineral compositions of titanomagnetite and ilmenite in vanadium-titanomagnetite of different mineral areas are significantly different. The grade of iron is 59.21%, 66.46% and 55.74%, the grade of TiO2 is 12.35%, 4.87% and 16.42%, and the grade of V2O5 is 0.928%, 1.142% and 2.07%, respectively, in iron concentrates from Panzhihua, Chengde and Chaoyang. Panzhihua ore has the highest value, followed by Chengde, while Chaoyang ore is the lowest.
