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 nutritional supplements for animals.
Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.
Phosphate rock.

phosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. The phosphates may be derived from a variety of sources, including marine invertebrates that secrete shells of calcium phosphate, and the bones and excrement of vertebrates. The thickest deposits of phosphorite form in areas ...
It was in 1881 that Captain J. Francis LeBaron, of the Army Corps of Engineers, discovered Florida's treasure in black phosphate pebbles in the Peace River. A "hard rock" phosphate reserve in North Central Florida was discovered next. Thus began Florida's phosphate mining industry. Florida's phosphate mining today accounts for about ...
Naturally occurring mineral products having sufficient phosphate content to be of commercial value are classified as phosphate rock. The grade or phosphate content of these products has been traditionally reported as percent Ca 3 (PO 4) 2, which is referred to as bone phosphate of lime (BPL), tricalcium phosphate (TCP), or triphosphate of …

Phosphate is a relatively low unit-value commodity. Therefore, most phosphate rock extraction operations tend to involve surface mining, large-volume extraction and reasonably low transport distances to major markets (Bartels & Gurr 1994). In comparison to many other mineral commodities, the demand for phosphate rock appears relatively predictable
