Use of Monocalcium Phosphate Monohydrate in Fertilizers:

Superphosphate fertilizers are produced by treatment of “phosphate rock” with acids (“acidulation”).

Using phosphoric acid, fluorapatite is converted to Ca(H2PO4)2:

Ca5(PO4)3F + 7 H3PO4 → 5 Ca(H2PO4)2 + HF

This solid is called triple superphosphate.

Several million tons are produced annually for use as fertilizers.

Using sulfuric acid, fluorapatite is converted to a mixture of Ca(H2PO4)2 and CaSO4.

This solid is called single superphosphate.

Residual HF typically reacts with silicate minerals co-mingled with the phosphate ores to produce hexafluorosilicic acid (H2SiF6).

The majority of the hexafluorosilicic acid is converted to aluminium fluoride and cryolite for the processing of aluminium.

These materials are central to the conversion of aluminium ore into aluminium metal.

When sulfuric acid is used, Monocalcium phosphate monohydrate contains phosphogypsum (CaSO4·2H2O) and is called single superphosphate.

At the same time, compressed air is used to atomize the phosphorus to oxidize and burn the phosphorus to produce phosphorus pentoxide.

Circulate phosphoric acid at the temperature of 30-40℃ along the top of the tower to cool the phosphorous pentoxide gas, and at the same time react with water to synthesize phosphoric acid.
