湿法磷酸的工艺研究进展

The Development of Study on Wet-process Phosphoric acid Technology

介绍了以磷矿为生产原料的硝酸法、盐酸法、硫酸法等湿法磷酸生产工艺,并对其工艺进行了说明和比较。突出了湿法磷酸生产中的除氟问题。指出了湿法磷酸产生磷石膏废物将是制约湿法磷酸生产的主要环节。

Some phosphoric acid production techniques are introduced,such as nitric acid technique,hydrochloric acid technique,sulfuric acid technique,which use phosphate rock as raw material. Introdutions and compares for above technology,and fluorine removeal are emphasized.The product phosphogypsum will restrict development of wet-process phosphoric acid.
