Manufacturing process of Phosphate fertilizers | Valco Group
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).
