钒新技术及钒产业发展前景分析

Analysis on New Vanadium Technologies and Prospects of Vanadium Industry

简要分析了国内外钒资源的情况与利用状况以及当前该领域已经取得的主要成绩。认为中国有比较丰富的钒资源,国家鼓励钒产业的发展,钒产品有比较稳定的市场需求,应该做好、做强钒产业。指出利用钒钛磁铁矿为原料提取氧化钒的清洁生产工艺可实现提钒废水和提钒尾渣闭路循环使用,解决了潜在的高氨氮—高钠盐提钒废水的污染问题,该项目的开发成功对全球钒产业将是一次革命性的技术创新,清洁、高效钒生产新技术是今后的发展方向。

Vanadium resources in domestic and international markets and their current utilization as well as major achievements in this field are analyzed in the present work. It is suggested that efforts should be made in China for a better and stronger vanadium industry based on rich vanadium resources, encourage- ment from Chinese government and relatively stable market demand for vanadium products. In the paper, it is pointed out that waste water and tailings from vanadium extraction can be recycled in the cleaner pro- duction process of vanadium oxide using vanadium-bearing titaniferous magnetite as raw material, which can solve the potential poUution problems caused by waste water with high ammonia nitrogen and sodium salt from the extraction. Cleaner and high efficient vanadium oxide production technology vailing technology in the future and the success the global vanadium industry. of this project is a revolutionary technical will be a preinnovation for
