Study on the Process of Extracting Vanadium Pentoxide from Stone Coal Boiling Roasting Material AITranslate
Abstract AITranslate
In response to the problems of large differences in raw materials,long process flow,low vanadium recovery rate(mostly below 60%),and high cost in extracting vanadium from stone coal boiling roasting materials,a process route of mixing acid,curing and leaching-oxidation neutralization-ion exchange-vana-dium precipitation with ammonium salt-calcination was adopted to extract vanadium.The experimental results show that under the conditions of sulfuric acid dosage of 20% of the raw material weight,curing temperature of 100 ℃,and curing time of 6 h,the vanadium leaching rate of stone coal boiling roasting material reaches 90.2%.The final product V2O5 powder quality is stable and reliable,which reaches the level of industry standards.This process has a short process flow,low engineering construction investment,high vanadium recovery rate,and low vanadium smelting cost,achieving good economic and technical indicators.
