中文摘要：

从高钙钒炉渣的钒的抽取被直接的烤并且苏打沥滤尝试。在不同温度的钒炉渣的氧化过程被 X 光检查衍射(XRD ) 调查，扫描电子显微镜学(SEM ) ，和精力散光谱学(版本) 。在钒的抽取上烤温度，烤的时间， Na2CO3 集中，沥滤的温度，稳固的比率的沥滤的时间，和液体的效果被学习。结果证明在钒炉渣的橄榄石阶段和尖晶石阶段完全在 500 和 800 点被分解吗？？

英文摘要：

The extraction of vanadium from high calcium vanadium slag was attempted by direct roasting and soda leaching. The oxidation process of the vanadium slag at different temperatures was investigated by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, and energy dispersive spectroscopy （EDS）. The effects of roasting temperature, roasting time, Na2CO3 concentration, leaching tem- perature, leaching time, and liquid to solid ratio on the extraction of vanadium were studied. The results showed that olivine phases and spinel phases in the vanadium slag were completely decomposed at 500 and 800℃, respectively. Vanadium-rich phases were formed at above 850℃. The leaching rate of vanadium reached above 90% under the optimum conditions： roasting temperature of 850℃, roasting time of 60 min, Na2CO3 concentration of 160 g/L, leaching temperature of 95℃, leaching time of 150 min, and liquid to solid ratio of 10：1 mL/g. The main impurities were Si and P in the leach liquor.
