Di-calcium phosphate by direct acidulation of phosphate rock

An investigation was undertaken to develop a process for producing di-calcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, mono-calcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, di-calcium phosphate should be formed

Dicalcium Phosphate From Rock Phosphate

Dicalcium Phosphate From Rock Phosphate Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. •Dicalcium phosphate is usually found as the dihydrate, but it can be thermally converted to the anhydrous form. It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C.

Production of dicalcium phosphate by treatment of

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
