Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material.

As a mineral resource, "phosphate rock" is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.
The Foskor PhosphorusPhosphates Mine is in Limpopo, South Africa. The site was first discovered in 1906 by Dr. E. T. Mellor. Production output of the Foskor PhosphorusPhosphates Mine was considered to be large size. Mine operations consist of surface workings. There is one known shaft.
various phosphate compounds. In South Africa, apatite ore is the most common source of phosphate rock and has been mined since the mid1900s in Phalaborwa, Limpopo (DMR, 2008). Also abundant in South Africa are sedimentary deposits of marine phosphorites along the west coast and in KwaZuluNatal (DMR, 2008). Foskor
Igneous phosphate rock can be found in Russia, Brazil, Canada, Mozambique, and the Republic of South Africa. Both igneous and sedimentary rocks that have been subject to high temperature and pressure may form metamorphic phosphate. Phosphate rock (whether igneous or sedimentary) is often called apatite.
Nov 30, 2016 Southern Africa finds itself at the center of the offshore bulk sediment mining debate as international companies rush to strip mine phosphate deposits in coastal waters of South Africa and Phosphate mining firms set sights on Southern Africa''s sea floor Phosphate is .
Apart from the high grade apatite breccia deposit under development, the complex is host to a number of economically attractive resources. Goldfields of South Africa owned and profitably operated a phosphate mine (Glenover) more than two decades before Ferminore acquired it in 2000 and started to monetize the remaining high grade phosphate ...

Acid, Pdeficient soils with a large capacity to immobilize P favour the rapid decomposition of apatite. Such soils are widespread in the east of South Africa and the possibility exists that Langebaan rock phosphate (Langfos) may be a more costeffective source of P than superphosphate on these soils. This study compared the effectiveness of granular Langfos to that of double superphosphate in ...

A Phosphate is a chemical derivative of phosphoric phosphate ion (PO 4) 3− is an inorganic chemical, the conjugate base that can form many different organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Of the various phosphoric acids and phosphates, organic phosphates are important in biochemistry and biogeochemistry (and, consequently, in ...

Apatite phosphates Gemstones index It is a calcium phosphate containing chlorine, fluorine and OH ions. According to the dominance of these three components is can be called fluorapatite, chlorapatite and hydroxyapatite .For sale in our boutiques.
apatite bearing zones which are the major source of South African phosphate production. The apatite is relatively coarse grained, with a well developed crystal structure, is hard and practically insoluble in water and weak acids such as citric acid. It is unsuitable as a direct application fertiliser and must first be treated with strong acids.
