Rock Phosphate. Rock phosphate, also known as phosphorite, is a sedimentary rock that is composed primarily of calcium phosphate (Ca3(PO4)2) and other minerals such as apatite and fluorapatite. It is typically found in shades of gray, brown, and black and has a granular or powdery texture.

in the rock phosphate process, the acidic solution was neutralized using liquid ammonia. The ammonia was diluted (15 ml NH 3 in 45 ml distilled water) due of liquid fertilizer from both rock phosphate and dolomite to the release of NOx gases when concentrated liquid ammonia solution was used which led to the subsequent dilution of the ammonia.
