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.
Egyptian phosphate rock grades between 18% P2O5 up to 30% P2O5, this determined according to mine location, Egypt considered on of the countries that own large deposit quantities of phosphate rock with different grades. The main tow locations or mines that rich of high grade phosphate rock are:

Phosphate Mining Manufacturing. Phosphate nutrients play an essential role in meeting the needs of a growing world. Mosaic mines phosphate rock in Central Florida's "Bone Valley," which stretches from Polk County southward through portions of Hillsborough, Manatee, Hardee, and DeSoto counties.
The Mining Process. Strip mining for phosphate rock violently transforms the environment, irreparably changing the character of the natural landscape. In many cases mines displace species and eat up thousands of acres of valuable habitat that are impossible to truly restore to their natural state.
This hardrock phosphate was mined in a region extending from Alachua to Citrus counties. The mining of pebble phosphate began in 1888 in central Florida and in the 1960s in Hamilton County. Today phosphate mining occurs primarily in the central Florida area (Polk, Hillsborough, Manatee and Hardee counties).
When the permitting process is complete, mine construction begins, including road building to the site. In Florida, the phosphate rock is extracted by a process referred to as stripmining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 3040 feet below ground.
As a mineral resource, “phosphate rock” is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.
