摘　　要：对贵州瓮福磷矿所制湿法磷酸进行了溶剂萃取的中间试验,考察中试设备及材质的适应性,对以磷酸三丁酯作萃取剂净化湿法磷酸的工艺流程和相关技术进行了研究,完成了3000t/aP2O5湿法磷酸净化中试试验。The pilot test for the purification of wet-process phosphoric acid produced at Guizhou Hongfu phosphate rock is studied in virtue of the process of solvent extraction. The feasibility of the pilot devices such as mixing-settling tank, reciprocating plate column, and their material is examined, the process and correlative technologies for wet-process phosphoric acid purification which used tributyl phosphate as extractant are studied, and the 3000 t/a wet-process phosphoric acid purification pilot test is accomplished.
