| Abstract: | The process, equipment, test result and technoeconomic appraisal of pilotplant test for production of SOP & coproductive crystallizing compound fertilizer from phosphogypsum in Gejiu City Chemical Fertilizer Plant are expounded. The test result shows that the process is feasible in techno economy , however it needs the KCl raw material with at least 60% K\-2O in order to obtain qualified SOP product and some equipment also need to be improved. In general, the SOP & coproductive crystallizing compound fertilizer products by means of the process have good quality and great market potential. |
