Abstract. Africa is the second largest of the world's continents; it has an area of about 30 million km 2, approximately three times the size of Europe, and a population approaching 500 million.From north to south in a straight line, the maximum distance is about 8,000 km, .
Acid, P-deficient 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 cost-effective 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 acid.The phosphate ion (PO 4) 3− is an inorganic chemical, the conjugate base that can form many different salts.In 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 ...
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 ...
various phosphate compounds. In South Africa, apatite ore is the most common source of phosphate rock and has been mined since the mid-1900s in Phalaborwa, Limpopo (DMR, 2008). Also abundant in South Africa are sedimentary deposits of marine phosphorites along the west coast and in KwaZulu-Natal (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.

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.

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.
