Abstract

Abstract

Based on the experiments of extracting vanadium from acid leaching solution of clay vanadium ore with N235, the factors influencing the extraction rate were studied. The influences of pH value, extractant concentration and phase ratio on the extraction rate were determined. The interaction effect during the three factors was determined by response surface methodology. The causes of interaction were analyzed by thermodynamics and solution chemistry. It is shown that the pH value and sulfur content in the extraction system greatly affect the vanadium components in the solution, and then affect the extraction rate. Meanwhile, the change of vanadium components also affects the extraction rate. Conclusively, the core mechanism of the interaction of the extraction system is the change of solution compositions caused by pH variation and the difference of extractant when facing different ions.
