Mineral Classification. Sedimentary. Description. 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

PHOSPHORITE Amethyst Galleries' Mineral Gallery

Phosphorite is a sedimentary rock of biochemical origin. Phosphorite results from the accumulation of the shells of certain microorganisms that incorporate phosphate minerals such as apatite in their shells.. Massive apatite is sometimes called phosphorite.

In addition to fertilizers, the phosphate minerals derived from phosphorite are utilized in flame-retardants, insecticides, fireworks, and a plethora of other products. Phosphates have also been heavily utilized in detergents, but have become less popular for this purpose over the last few decades.

phosphate mineral Description, Uses, & Facts Britannica

Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. Phosphates can be grouped as: primary phosphates that have crystallized from a liquid; secondary phosphates formed by the alteration of primary phosphates; and rock phosphates formed from phosphorous-bearing organic material.

OverviewApplicationsExamplesNickel–Strunz classification -08- phosphates

Phosphate minerals contain the tetrahedrally coordinated phosphate (PO4 ) anion along sometimes with arsenate (AsO4 ) and vanadate (VO4 ) substitutions. Chlorine (Cl ), fluorine (F ), and hydroxide (OH ) anions that also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.

In the SCS, phosphorite is also a major offshore mineral resource, a source of phosphate for chemicals and fertilizers. Significant deposits of phosphorite are found in the Xisha Islands (Ritterbush, 1978). Phosphorite is also formed in regions of oceanic upwelling where large volumes of phosphate-rich cold water rise from great depths to the

Phosphorite-type rare earth deposits, which are one of the important types of rare earth elements (REE) ore deposits, have attracted increasing attention because of the extreme enrichments in heavy rare earth elements (HREE), including Yttrium (Y). In this study, in situ geochemical analyses of apatite grains from Zhijin phosphorites were conducted using electron probe microanalysis (EMPA) and

J.P. Attfield, in Encyclopedia of Materials: Science and Technology, 2001. 4.9 Minerals. Several hundred phosphate minerals are known, virtually all of which are orthophosphates. The important mineral apatite, ideally Ca 5 (PO 4) 3 X (X=F, Cl, OH), is found in igneous pegmatite rocks and hydrothermal veins. Poorly crystalline or amorphous phosphorite sediments made from the hard remains of

Phosphorite Ore Mining Solution Mineral Processing

Forward-reverse flotation (reverse-positive) flotation and double-reverse flotation can achieve the purpose of enriching phosphorus minerals by removing silicate minerals and carbonate minerals, so it can deal with refractory sedimentary calcium calcium (magnesium) ) Quality phosphorite rock; 4. Stage flotation can treat gangue minerals and

Mineral vs Phosphorite What's the difference? WikiDiff

As nouns the difference between mineral and phosphorite is that mineral is (geology) any naturally occurring inorganic material that has a (more or less) definite chemical composition and characteristic physical properties while phosphorite is (mineralogy) a sedimentary rock rich in phosphate minerals such as apatite. As an adjective mineral is of, related to, or containing minerals.

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. The United States is the world's leading producer and consumer of phosphate rock, which is
