• Stone coal
• Sulphuric acid leach
• Vanadium species
• Ion exchange

The species of vanadium extracted by a weak base anion resin D314 from sulphuric acid leach solution of stone coal was investigated. The saturated adsorption capacity of vanadium on the resin was found to be up to 501 mg/mL wet resin with a distribution ratio of 950 at pH = 3-4 and 15 degrees C using static adsorption method. Vanadium was adsorbed in the form of V(10)O(28)(6-) and HV(10)O(28)(5-). The study provides the theory and fundamental basis for the industrial application of weak base resins for extraction of vanadium from acid leach solution of stone coal.
