Abstract

Abstract

Based on high carbon stone coal of Guangwang of Sichuan,on the basis of chemical analysis, petrographic analysis and electron probes, recovering vanadium experiment from high carbon stone coal by aid leaching was carried. The result show that the optimum vanadium extraction rate is respectively 54.7% and 72.86% after one and two steps atmospheric leaching and two pressure acid leaching. This two methods do not have high leaching rate of vanadium, because of high carbon content and minerals of stone coal, and carbon have a complex behavior in the leaching process.
