Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than .
Phosphate Rock Statistics and Information Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus.

Florida phosphate mining dates back to the first hard rock deposits found near Hawthorne in Alachua County in 1883. Endurance was imperative in the early years when phosphate mining was done with wheelbarrows, picks and shovels. Next came mule-drawn scrapers. Mechanized excavation began between 1900 and 1905 with steam shovels.
The exact phosphate content of the phosphate rock mined in 2015 is not available, but in the latest five-year period for which ore grades are available, 2009-2013, the grade of US phosphate rock varied from 28.5 to 29.0 percent P 2 O 5. As of 2016, remaining reserves of phosphate rock in the United States totaled 1.1 billion metric tons.
Phosphate ore in South Australia was discovered at Clinton on Yorke Peninsula in 1899. Subsequently some 90 deposits and occurrences have been identified. South Australia has a long history of production of phosphate rock, mainly for use as a fertiliser.
