    摘要
  • 摘要: 评述了石煤钒矿焙烧提钒的研究进展，探讨了焙烧工艺可能的应用场景，通过实例论述了不同焙烧工艺的优势与不足，并对石煤钒矿焙烧提钒这一领域的发展现状、行业难点进行了总结与展望。石煤钒矿中的钒主要以类质同相形式赋存，焙烧是提钒的关键。传统的焙烧工艺有钠化焙烧、钙化焙烧、复合添加剂焙烧和无盐焙烧等，这些工艺比较成熟但是需要控制污染；新近提出的焙烧工艺有微波焙烧、碱熔焙烧、氯化焙烧和低温硫酸化焙烧等，其中微波焙烧的概念提出较早，但是最近才取得明显的理论与实践进展，碱熔焙烧在提升钒价态这方面有较好效果，氯化焙烧和低温硫酸化焙烧符合绿色低碳的发展理念，同时可以获得较理想的提钒指标。
    Abstract: The research progress of vanadium extraction from stone coal vanadium ore by roasting was reviewed. The possible application scenarios of roasting process were discussed. The advantages and disadvantages of different roasting processes were discussed through examples. The development status and industry difficulties of vanadium extraction from stone coal vanadium ore by roasting were summarized and prospected. Vanadium in stone coal vanadium ore mainly exists in the form of isomorphism, and roasting is the key to extracting vanadium. Traditional roasting processes include sodium roasting, calcification roasting, composite additive roasting and salt-free roasting. These processes are relatively mature but need to control pollution. The newly proposed roasting processes include microwave roasting, alkali fusion roasting, chlorination roasting and low-temperature sulfation roasting. The concept of microwave roasting was proposed earlier, but obvious theoretical and practical progress has been made recently. Alkali fusion roasting has a good effect in improving vanadium valence. Chlorination roasting and low-temperature sulfation roasting are in line with the development concept of green and low-carbon, and can obtain ideal vanadium extraction indicators.
