| Abstract: | A computer program is developed for the wet phosphoric acid process using Saudi phosphate ore. The program concentrates on the heart of the process that is the acidulation crystallization step. The key parameters of the program are obtained from micropilot plant continuous experiments performed at our laboratory using different types of Saudi phosphate ores with different chemical, physical and minerological properties. The program is used to correlate the main operating and design parameters with the ore measurable characteristics. |
