Synopsis

Molten vanadiferous titania slag containing 2,0 wt % V2O3 was sulphided with elemental sulphur with an addition of MgO under reducing conditions at around 1600°C to form iron-vanadium rich sulphide. Sulphided slags after fine grinding were subjected to gaseous sulphation at 450°C with S02 + O2 mixture to obtain water soluble VOSO4. Water leaching at room temperature gave 88.2% vanadium extraction calculated on the basis of the vanadium content in the slag. A slightly lower degree of extraction was obtained by sulphiding the slag with S2 + C at 1200°C and then sulphation with water leaching.
