beneficiation process of phosphoric acid production

Production of phosphoric acid by HCL leaching process ...

2.1 PRODUCTION PROCESS 2.1.1 Phosphoric Acid Manufacturing Figure 2-1 describes the phosphoric acid manufacturing and phosphate fertilizer production process. Phosphoric acid can be manufactured by one of two processes: a wet process or a thermal process. Each of these processes produces very different grades of phosphoric acid.
