Superphosphate Mining

Superphosphate - an overview ScienceDirect Topics

2012-1-10  Triple Superphosphate (TSP) As in the case of SSP, the rock phosphate is ground to a fine mesh and reacted with concentrated phosphoric acid (52 to 54% P 2 O 5) in a cone mixer: C a 10 P O 4 6 F 2 + 14 H 3 P O 4 → 10 C a H 2 P O 4 2 + 2 H F. It is then fed to a continuous den and piled for curing.

Phosphate fertilizers

Triple Superphosphate is produced by grinding and acidulating rock phosphate. Grinding increases the reactivity, acidulation with phosphoric acid makes the phosphate watersoluble enabling the plant to absorb the fertilizer. The high water solubility of P2O5 in Triple Superphosphate increases the effectivity of the fertilizer. View product
