World phosphate deposits Phosphate rock (PR) is a general term that describes naturally occurring mineral assemblages containing a high concentration of phosphate minerals. The term refers to both unbeneficiated phosphate ores and concentrated products.
But we can provide more by mining phosphate rock and turning it into fertilizer to spread on the land. It takes one ton of phosphate to produce every 130 tons of grain, which is why the world mines about 170 million tons of phosphate rock every year to ship around the world and keep soils fertile.

Here it is sluiced with streams of high pressure water to the suction of a large centrifugal pump which transports the matrix slurry to the washing plant which may be a mile or two away.
Phosphate Rock. 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.
