摘 要:磷矿中伴生的氟资源主要以氟磷灰石的形式存在,在湿法磷酸生产过程中逸出的氟会被水吸收转化为氟硅酸。氟硅酸的回收利用或梯级利用是目前磷肥行业和氟化工行业研究的热点和重点,其可作为生产无水氟化氢的原料,不仅可以提升企业的经济效益,又有助于解决我国萤石资源短缺的难题。磷肥企业可依据氟硅酸法制无水氟化氢开发一条氟化工产业链,发展含氟湿电子化学品以及含氟电子特气,例如电子级氢氟酸、电子级氟化铵、四氟化碳以及三氟化硼等高端产品,提高产品的附加值。Fluorine resources are often associated with phosphate rock,and the fluorine mainly exists in the form of fluorapatite.The fluorine released during the production process of wet-process phosphoric acid is absorbed by water and converted into fluorosilicic acid.The recycling or cascade utilization of fluorosilicic acid is currently a hot topic and focus of research in the phosphate fertilizer industry and fluorine chemical industry.It can be used as a raw material for producing anhydrous hydrogen fluoride,which can not only improve the economic benefits of enterprises,but also help solve the problem of fluorite resource shortage in China.Phosphate fertilizer enterprises can develop a fluorine chemical industry chain based on the fluorosilicic acid method to produce anhydrous hydrogen fluoride.They can develop high-end products such as fluorine-containing wet electronic chemicals and fluorine-containing electronic specialty gases,including electronic grade hydrofluoric acid,electronic grade ammonium fluoride,carbon tetrafluoride and boron trifluoride,to increase the added value of products.
