Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.

In current ammonium phosphate production technologies, apparatuses of various designs are employed without mechanical mixing. One of these (Fig. 2) represents a horizontal or a vertical tube with side tubes for acid and ammonia injec-tion. It has been experimentally established that ammonia must be injected through a tube that does not disrupt ...

Phosphate, (MAP), NH4(H2PO4), Di-Ammonium Phosphate (DAP), (NH4)2HPO4, are produced by the reaction of ammonia on phosphoric acid solution. The slurry is then granulated at high temperature leading to the fertilizer product. Triple Super Phosphate (TSP) results from the reaction of ph osphoric acid on the phosphate ore.

This process breaks down the rock phosphate, releasing phosphorus in a form that plants can easily absorb. The sulfuric acid also reacts with the rock phosphate, creating calcium sulfate, which is a source of sulfur. So, not only does superphosphate provide phosphorus, but it also delivers sulfur to your plants, ensuring their overall health ...
