A process is provided for recovering vanadium values from highly alkaline, calcium-rich calcines, which are usually the roasted product of low-grade vanadium-bearing calcitic ores. The process involves slurrying the calcine in water and carbonating the slurry to a pH of 5.0 to 9.0 to extract the soluble vanadium species from the slurry. A basic anion exchange resin is added to the carbonated slurry thereby increasing the vanadium recovery by shifting the extraction equilibrium. |
