phosphate in igneous rocks

Phosphate Minerals in Terrestrial Igneous and

Phosphorus is a ubiquitous although minor component of most igneous and metamorphic rocks. Under the normal oxidative conditions of the Earth’s crust and upper mantle, phosphorus is present as phosphates, and Koritnig (1978) lists over 200 phosphate minerals.

Sedimentary and Igneous Phosphate Deposits: Formation

Phosphorus is the central ingredient in fertilizer that allows modern agriculture to feed the world’s population. This element, also critical in a host of industrial applications, is a nonrenewable resource that is sourced primarily from the phosphatic mineral apatite, hosted in sedimentary and igneous ores.

Sedimentary and Igneous Phosphate Deposits: Formation

Igneous and sedimentary phosphate rocks are the two main RP types in the world (Ptáček, 2016; Pufahl and Groat, 2017). The crystal structure of igneous phosphate rocks is coarser, lesser porous

Phosphate Rocks IntechOpen

2018-8-16  Nearly all igneous rocks contain some phosphate, even if it is only ~0.1% (0.2% P2O5on average in lithosphere), with nearly all of it in the form of apatite. Sedimentary rocks generally contain rather less (~0.1% P2O5on average). Sedimentary phosphorite is believed to originate from widely dispersed apatite mainly in igneous rocks. 7.1.1.

2021-8-18  Apatite is the name of phosphate based minerals in phosphate ore whether the ore is of an igneous or sedimentary origin. The majority of the phosphate rock resources are sedimentary, i.e. they originate from remains of marine life in regions that were once covered by seas, and got transformed into substantial phosphate deposits over the millennia.

Phosphate Deposits USGS

2010-8-9  The earth's crust contains about 0.27 percent P205. Common igneous rocks, such as granite, diorite, gabbro, and peridotite, contain only from about 0.005 to 0.4 percent P205, but some of the less common alkalic rocks, such as ijolite and turjaite, can contain more than 1 percent. Variations in phosphate content of igneous rocks generally parallel those of ilmenite and magnetite.Apatite is slowly soluble in neutral or alkaline waters, and its solubility increases with increasing acidity, decreasing hardness, and decreasing temperature. Apatite may survive rock weather ing for a time to form a phosphate-rich residuum, but it breaks down under prolonged exposure. Some of it may be redeposited locally. In high-calcium soils and rocks, apatite is again the min eral formed. Where the terrane consists of igneous rocks,

Geology of Phosphate Rock in China: Distribution, Rock

2016-11-1  Marine sedimentary PR is the class of phosphate- resource-bearing rocks most widely distributed in the world. The world’s largest sedimentary phosphate de-posits are found in northern Africa, China, the Middle East and America. The second most common are igneous rock phosphate deposits, mainly found in Brazil, Canada, Russia and South Africa.

Phosphate Rock USGS

2021-2-4  Significant igneous occurrences are found in Brazil, Canada, Finland, Russia, and South Africa. Large phosphate resources have been identified on the continental shelves and on seamounts in the Atlantic Ocean and the Pacific Ocean. World resources of phosphate rock are more than 300 billion tons. There are no imminent shortages of phosphate rock.

Phosphate Minerals an overview ScienceDirect Topics

Another source is dissolved phosphate minerals from igneous and metamorphic rocks. Phosphate rock is a nonrenewable resource that takes 10–15 million years to cycle naturally. All crops need phosphorus, and most must be supplied in fertilizer because natural soil supplies are too low to fill crop demand.

Overview of South Africa's Phosphate Fertiliser Industry

Phosphate rocks are a primary source of phosphorous. Apatite is the most common igneous source of phosphate. To be used in the fertiliser industry, phosphate rock and its concentrate need to contain at least 30 percent phosphorous pentoxide (Pb 2O 5) and reasonable amounts of calcium carbonate (CaCO

Fertilisers Safer Phosphates
