摘　　要：利用石煤钒矿浸出液中的钒和铁直接制备钒酸铁,考察了氧化剂种类及过量系数、时间、pH、温度对沉淀钒酸铁的影响。确定了石煤钒浸出液沉淀钒酸铁的最佳工艺参数：氧化剂氯酸钠的过量系数1.4、反应时间5h、pH=2.5、反应温度90~95℃,V2O5沉淀率达到93.73%。Ferric vanadate was prepared dosage of oxidant, reaction time, pH from coal vanadium ore leaching solution. Th value, and temperature on precipitation were precipitation rate is 93.73% under the optimum conditions including dosage of sodium of theoretical value, reaction time of 5 h, pH value of 2.5, and reaction temperature e e in chl of fleets vesttg of type and ated. V2O5 orate of 1.4 times 90-95℃.
