Upgrading of raw vanadium titanomagnetite concentrate
To obtain a high-quality vanadium titanomagnetite concentrate, the raw vanadium titanomagnetite concentrate was upgraded by fine grinding in a ball mill (ZQMF250x100) and magnetic separation using a counter-rotation wet drum separator (F800x300 mm). The fine grinding was carried out by wet grinding at a solids to water ratio of 500:275 by mass).
