石煤提钒的历史概况

Release date:2018-12-19  source:中南选矿网  Browse times:370
        上世纪20~30年代,美国从内华达州的卡林页岩(石煤)中提,获得成功。此项成果是由P.T.布鲁克斯等研究的,试验结果采用食盐焙烧、稀硫酸浸出、萃取、沉淀偏钒酸铵的流程[12]。

自1912年Bleecker用钠盐焙烧-水浸工艺回收钒的专利公布以来,一直沿用至今。焙烧时因食盐分解产生Cl2、HCl等有害气体,严重污染环境,腐蚀厂房。例如,在湖南岳阳、崇阳地区等钒厂,周围大片草木枯死,农工关系紧张,这个工艺已成为困扰钒厂发展的主要问题。我国对环保意识日益增强,添加食盐焙烧的厂房相继被取缔,新型环保生产工艺的研究势在必行。
