| Abstract: | Using as stone coal vanadium ore which is of 0.85% V2O5 and whose calorific value is 5 000～6 500 kJ/kg,adopting the process of generation in circulating fluidized bed,extraction with fly ash and cement production with tailings,leaching rate of vanadium is up to 82%～83% and recovery rate reaches 51.71%,1 t V2O5 can produce 4～5 t by-product silica.The industrialized trial production showed that the process was of better social and economic benefits,enhancing comprehensive utilization of stone coal and effectively reducing cost of production. |
