Abstract: The experiments on vanadium extraction from stone coal of a place in HuBei indicate that the method of no-salt-roasting and low acid leaching could get better result,after comparison of five different technologies.The research on such processing parameters as roasting temperature,roasting time,dosage of sulfuric acid and acid leaching time indicates that the extraction rate of vanadium could reach 77.51%～80.33% under the conditions of material particles of -0.147mm,roasting temperature 900℃ ～950℃,roasting time 1～1.5h,， dosage of sulfuric acid 2.5% and acid leaching time 1h at normal leaching temperature.

Key words: Stone coal, Vanadium, Extraction rate of vanadium
