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.
Phosphate mining began in Florida in 1883 near Hawthorne in Alachua County. This hard-rock 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.
Alibaba.com offers 4,430 rock phosphate products. About 60% of these are phosphate fertilizer, 4% are phosphate, and 1% are feed grade minerals & trace elements. A wide variety of rock phosphate options are available to you, such as rock phosphate, ssp, and tsp.

Flotation of AI-Jalamid phosphate rock (sedimentary type with high carbonates and low silica content) found in northern Saudi Arabia was
Phosphate Rock Basics. Utah hosts a long list of economically important industrial minerals, and phosphate rock is definitely on the list. Phosphate rock has over 100 years of history of Utah production, primarily for use in fertilizer.
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).
Like all other food additives, GRAS substances and ingredients added to food, monocalcium phosphate must always be listed on the food label if it is used in a food. Monocalcium phosphate might also be identified on food labels as calcium dihydrogen phosphate, which is a synonym for monocalcium phosphate.
Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and consumer of phosphate rock, which is used to manufacture phosphate fertilizers and industrial products.
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.
phosphate by carbonate. It has been shown that the solubility of carbonate substituted phosphate rocks is higher than the solubility of pure fluor-apatite with little or no carbonate-substitution (Chien and Hammond 1978). Increasing carbonate substitution in the phosphate rock …

Description Christmas Island Rock Phosphate (CIRP) was formed by slow phosphatisation of the parent sedimentary and volcanic rocks over millions of years.
supplementation of the diet with phosphate in some form is a very common practice in farm animals. Materials used include rock phosphate (defluorination may be necessary), sodium dihydrogen phosphate produced by the agricultural chemical industry, calcium triphosphate and bone meal or flour.
Phosphate rocks: Phosphorus, an element of phosphate, strengthens roots and helps them to mature early. Table 7.6 shows the rock phosphate analysis which contains 26.7% P 2 O 5 . Rock phosphate is recommended in organic farming as a source of phosphorus for plants.
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which 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 ).
