Phosphate Fertilizer Production Process

Phosphate fertilizers – Manufacturing process of Phosphate ...

A weak phosphoric acid (40-55%) is produced from the reaction of PR with sulfuric acid, using a wet- process. The obtained phosphoric acid is then used in the production of a series of liquid or solid fertilizers. The most important ones are single and triple superphosphates (SSP, TSP) and ammonium phosphates (MAP, DAP).

Phasphoric Acid and Phosphatic Fertilizers: A Profile

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. Acid produced via the wet process is typically referred to as merchant-grade phosphoric acid. During the wet process ...
