Phosphate rock is obtained from geological deposits. Its primary constituent is apatite, a calcium phosphate mineral. Phosphate rock is the basis material for almost all phosphate fertilizers, either as such or transformed into phosphoric acid. When added to the soil, phosphate rock slowly dissolves and gradually releases its nutrients.

I think that there are 2 types of rock phosphate. one is hard rock phosphate not very useful for produce and the other is soft rock phosphate-the soft rock that we apply is called cal-phos and i think that its 0-3-0 3 available and 20 total. it is a brown, granular material which softens up when wet.
Phosphate rock contains many impurities, such as chlorides and fluorides, which make phosphoric acid very corrosive to metals. the highly corrosion-resistant tube grade sanicro 174 28 is specially developed to replace graphite tubes in heat exchangers for concentrated phosphoric acid. with proper heat exchanger design, tubes in sanicro 174 28 outperform graphite tubes by several years.
