Rapid Vanadium Extraction from Roasted Vanadium Steel Slag via a H₂SO₄-H₂O₂ System: Process and Mechanism.

ABSTRACT: A H₂SO₄-H₂O₂ system was developed to enhance the efficacy of vanadium extraction from roasted vanadium steel slag. The optimum parameters and the behavior of vanadium extraction were investigated systematically. When 1 mL of H₂O₂ per gram of vanadium slag was added to a leaching mixture at 50 °C, along with 30% H₂SO₄, 80.5% of vanadium extraction was achieved within 15 min. However, without H₂O₂, only 58.5% of vanadium extraction was achieved at the same leaching time. The H₂SO₄-H₂O₂ system facilitated the dissolution of metallic ions in a short time and then triggered the production of strong oxidizing substances, such as HO^•
