    [PDF] Source separation of V and Fe by two

    A method of two stage selective leaching for separation of V and Fe during V extraction from stone coal was developed. In the primary procedure stone coal was roasted in an inert atmosphere at 900 C for 1 h, and then the roasted product was leached for Fe removal in 7% (vol%) H2SO4 at 30 C for 30 min when the liquid-to-solid ratio (L/S) was 3 : 1 mL g−1.

    The separation and recovery of sulfuric acid from an acidic leaching solution of stone coal containing 110g/L of H 2 SO 4 and 1.98g/L of vanadium and other metal ions with the use of TEHA was investigated. Vanadium valence has a significant effect on the separation of sulfuric acid and vanadium because of the speciation of the anion VO 2 SO 4 − of V(V) in the solution.
