| Abstract: | 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 3 000 t/a wet-process phosphoric acid purification pilot test is accomplished. |
