We present an optimized magnetic separation process to improve the recovery of high-content vanadium and titanium concentrates from vanadium‑titanium magnetite (VTM) ore. The ore chunks were crushed using jaw crushers and then grinded in a laboratory rod mill for different grinding times and studied.Gas-based reduction roasting magnetic separation process was conducted to separate and recover iron and titanium from oxidized vanadium titano-magnetite (VTM). The effects of reduction temperature, gas composition, reduction time, grinding fineness, and magnetic field intensity on the efficiency of Fe-Ti separation were investigated.Separation and recovery of iron and titanium from oxidized

Geophysical techniques, such as magnetic and geoelectric ones, are useful for ore deposit exploration, represented by titanomagnetite. Titanomagnetite is a mineral composed of oxides of titanium and iron. Forty-seven magnetic profiles have been measured using two proton magnetometers to cover the study area with a direction Ti in vanadium titanomagnetite concentrate is converted into Na2TiO3 at below 1150°С and then forms CaTiO3 by reduction as temperature increases to about 1200°С. “New process of metallization reduction-magnetic concentration-electroheat melting separation for vanadium titano-magnetite,” J. of Northeastern University (Natural Investigation of Vanadium Titanomagnetite Concentrate
