Phosphate Rock an overview | ScienceDirect Topics
Typical Florida pebble phosphate rock contains about 36% fluoride expressed as elemental fluorine, and approximately 32% of this is released during the acidulation process (Pettit, 1951) Almost all of the fluoride vapors are evolved in the mixer and den although a slight evolution of vapor occurs during subsequent handling and storage operations The composition of mixerRock phosphate is a naturally occurring ore of marine sedimentary origin It may have a composition of 0300, but the grade is noted as 030, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops Many of the mines that produced rock phosphate are closed, and most of the marketed rock phosphate comesPhosphate Rock an overview | ScienceDirect Topics

PHOSPHATE ROCK phosrock
Phosphate rock is the basis material for almost all phosphate fertilizers, either as such or transformed into phosphoric acid When added to the soil, phosphate rock slowly dissolves and gradually releases its nutrients This product isphosphorite, 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 characterized by carbonaceousphosphorite | Definition, Formation, & Uses | Britannica
