The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world Some phosphate rock is used to make calcium phosphate Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as highgrade ore (+30% P 2 O 5), mediumgrade ore (20%–30% P 2 O 5), and lowgrade ore (15%–20% P 2 O 5) The very highgrade ore blends with mediumgrade ore for direct sale The highgrade ore is mined, crushed, and sold to various fertilizer plantsPhosphate Rock an overview ScienceDirect TopicsApr 06, 2020 What is Rock Phosphate, Exactly? Rock phosphate also referred to as phosphate rock or phosphorite, is a type of nondetrital sedimentary rock packed with phosphate mineralization, including apatite In addition to being an essential organic source of phosphorus, phosphate rock also contains limestone, clay, and some other essential trace mineralsWhat Is Rock Phosphate and How to Use It in Your Garden
