Phosphate Rock - an overview | ScienceDirect Topics
Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as high-grade ore (+30% P 2 O 5), medium-grade ore (20%–30% P 2 O 5), and low-grade ore (15%–20% P 2 O 5). The very high-grade ore blends with medium-grade ore for direct sale. The high-grade ore is mined, crushed, and sold to various fertilizer plants.
Gaia Green Rock Phosphate - Jons Plant Factory
Gaia Green Rock Phosphate is a naturally occurring mineral which is ground to a fine dust to improve the release of phosphorus for plant growth. This powdered mineral is then granulated with a natural binder called lignosulfonate. This granulating process produces a consistently sized particle which is easy to apply and is completely free of dust.
Phosphorite - Wikipedia
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite varies greatly, from 4% to 20% phosphorus pentoxide. Marketed phosphate rock is enriched to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-liming, magnetic separation or flotation. By …
Phosphate Rock
Phosphate Rock is an excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30 percent total phosphate (3-8 percent available) and 48 percent calcium (as CaO). Phosphate rock has approximately one fifth the neutralizing power of lime. Natural rock phosphates are from deposits of apatite rock formed eons ago by sea life that left behind fossils and shells composed primarily of calcium phosphates.

Phosphate Rock | Minerals Education Coalition
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.

Mineral Resource of the Month: Phosphate Rock | EARTH Magazine
Phosphate rock deposits can be sedimentary or igneous, but more than 80 percent of the world’s current production of phosphate rock is mined from sedimentary deposits formed by deposition of phosphate-rich materials in marine environments. Large sedimentary deposits are located in China, the Middle East, northern Africa and the United States.
Phosphate - Wikipedia
Phosphorus comprises 0.1% by mass of the average rock (while, for perspective, its typical concentration in vegetation is 0.03% to 0.2%), and consequently there are quadrillions of tons of phosphorus in Earths 3 * 10 19 ton crust, albeit at predominantly lower concentration than the deposits counted as reserves from being inventoried and cheaper to extract; if it is assumed that the phosphate …

Reserves and Resources DC World Phosphate Rock
Information circulating on the Internet and in conventional literature for several years has suggested that phosphate rock reserves are dwindling. This is a critical issue because phosphorus (from phosphate rock) is one of the three key elements needed for optimum plant growth (along with nitrogen and potassium).
