Phosphate fertilizers Manufacturing process of Phosphate

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). Usually the plants are using flexible process technologies, allowing the manufacture of at least two products with interchangeable lines (e.g. TSP and DAP combination).

Phosphorus Fertilizer Production and Technology

History of Phosphate Fertilizer • Early sources were mostly animal based ̶ bones, guano, manure • Treatment of bones with acid to increase P solubility started early to mid 1800s • Sulfuric acid treatment process of bones and P minerals (apatite) was patented in mid 1800s. • Today most P fertilizer production is based on acidification of apatite. from phosphate rock (PR) Guano mining
