Due to the lack of mineral sources of Vanadium (V) in many parts of the world and its recent applications in the field of medicine (as an anti-tumor agent), one of the biggest sources of V is the extraction of V as VO from steel slag in melting process. In this study, the pyro-hydrometallurgical process has been investigated for the extraction of V from steel slag created in a convertor. To get an optimum process of salt roasting, the effect of roasting temperature, time, salt value, slag particle size, and cooling method have been investigated. For this purpose, slag samples were roasted with sodium carbonate and then dissolved in water. The amount of VO obtained by optical spectrometry is the efficiency criterion of this process. Results showed that the optimum condition for the extraction of VO from steel slag was 15 wt % of NaCO as a salt roasting agent and hating for 60 min at 1100 °C.
由于世界上许多地区缺乏钒（V）的矿产资源，且钒最近在医学领域有应用（作为一种抗肿瘤剂），钒的最大来源之一是在熔炼过程中从钢渣中提取五氧化二钒（VO）。在本研究中，对火法湿法冶金工艺从转炉产生的钢渣中提取钒进行了研究。为了获得盐焙烧的最佳工艺，研究了焙烧温度、时间、盐用量、炉渣粒径和冷却方法的影响。为此，将炉渣样品与碳酸钠一起焙烧，然后溶于水。通过光谱法获得的五氧化二钒量是该工艺的效率标准。结果表明，从钢渣中提取五氧化二钒的最佳条件是以15 wt%的碳酸钠作为盐焙烧剂，在1100℃下焙烧60分钟。
