| Abstract: | TheSsampleScontaining 0.506% V2O5,Stotal carbonS36.56%,Sbelongs to low grade stone coal that contained vanadium. The calorific value of this sample isS13.27 MJ/kg, which can be used for roasting. The detailedSexperimental research onSroasting temperature,Sroasting time,Sparticle size,leaching time,SleachingStemperature,Sleaching agentSandSacidity had be done.Finally we choosed the blankSroasting- acid leachingS(addingSadditives)Sprocess with the leaching rate of V2O5S70.41% |
