Making superphosphate involves chemically treating rock phosphate, quarried in the US, Egypt, Tunisia and elsewhere. The production process. One of the basic materials needed to make superphosphate is sulfuric acid. This is produced by burning sulfur and dissolving the fumes in water. Rock phosphate is then dissolved in the acid.

Process for the production of urea superphosphate, which comprises reacting ground urea and ground phosphate rock with sulfuric acid in a single stage, in the presence of gypsum or phosphogypsum, or calcium sulfate monohydrate or anhydrous. Phosphoric acid may be added to the reaction mixture. The reagents may be added simultaneously to a reactor.

The main aim of the super phosphate process is to convert this PO4 into a soluble form. • The phosphate rock is crushed into fine particles, • The rock is reacted with concentrated sulphuric acid, converting much of the PO4 into a soluble form. Most of this reaction occurs quickly, but it will continue slowly over the next few days ...

The general chemical reaction is Ca₃ (PO₄)₂ [rock phosphate] + 2 H₂SO₄ [sulfuric acid] → Ca (H₂PO4)₂ [monocalcium phosphate] + 2 CaSO₄ [gypsum]. SSP can easily be produced on a small scale to meet regional needs. Since SSP contains both monocalcium phosphate (MCP, also called calcium dihydrogen phosphate) and gypsum, no ...

Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Unless carefully managed, these waste products can leach heavy metals into groundwater or nearby estuaries.
