Vanadium Recovery from Oil Refinery Sludge Using

The experimental data illustrated that more than 65% of vanadium in fly ash can be extracted in one stage of leaching by sulfuric acid (96%) with liquid volume ratio to solid weight 0.1 l/g at 65oC. Under the optimum operating conditions of ELM technique, more than 86% of vanadium was extracted in 1 hr at ambient temperature.
