Production of dicalcium phosphate by treatment of phosphate rock

This paper presents results laboratory experiments to test a new process for manufacture of dicalcium phosphate. The process is based on the nitric acidulation of phosphate rock concentrate, followed by neutralization of the extract liquor with calcium carbonate. The precipitated dicalcium phosphate is then separated from calcium nitrate solution by filtration. The dicalcium phosphate thus ...

Phosphate Rock - an overview | ScienceDirect Topics

Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate. The wet chemical phosphoric acid treatment process, or ‘wet process’, in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 · 2H 2 O):

Tricalcium phosphate - Wikipedia

Tricalcium phosphate (sometimes abbreviated TCP) is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2.It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL).It is a white solid of low solubility. Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite.. It exists as three crystalline polymorphs α, α', and β.
