Aim to the separation problem of high concentration V–Fe in stronger acidic leaching solution of vanadium slag, a novel chelating extraction system is proposed to separate V and Fe. Influence factors including initial pH value, the extractant concentration, the phase ratio, temperature and time are investigated. The experiment results show that single extraction rate of V and Fe reach 85.57 and 0.39% respectively, when pH value is −0.4, organic phase composition is 30% Mextral 973H + 70% sulfonated kerosene oil, O:A = 1:1, stirring time is 10 min, extraction temperature is 30 °C. The industrial experiment results of three levels countercurrent extraction show that the total extraction rate of vanadium and iron can reach 97.44 and 0.23%, separation factor is 6410. The effective separation of V and Fe in high acid and high iron solution can be accomplished.
