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.

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 marine organisms are the principal commercial source of phosphates,

Phosphate. Phosphates are an essential aspect of the function of the human body, particularly in the systems relied on in the production of energy, as well as in bone formation. A phosphate is a molecule created by the combination of one phosphorus atom, and four atoms of oxygen, stated in the chemical form PO 4.

Calcium phosphate Ca3(PO4)2 - PubChem

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.

Fertilizer - Wikipedia

Phosphate fertilizers are obtained by extraction from phosphate rock, which contains two principal phosphorus-containing minerals, fluorapatite Ca 5 (PO 4) 3 F (CFA) and hydroxyapatite Ca 5 (PO 4) 3 OH. These minerals are converted into water-soluble phosphate salts by treatment with sulfuric (H 2 SO 4) or phosphoric acids (H 3 PO 4).

As late as the 1960s phosphate rock mining contributed about ten percent of the total value of Tennessee mineral production. Beginning in the 1970s, the number of operations dropped significantly, and by the 1980s only two were left. In 1991 both operators announced closings, ending phosphate mining and refining in Tennessee.
