Phosphorus is produced almost exclusively through the mining of finite phosphate rock (PR) deposits of either sedimentary (87%) or igneous (13%) origin. From the overall production volume, 83% (46 Mt P2O5) is used for chemical fertilizers and the rest is used for other industrial purposes [3]. The currently mostly linear P supply chain includes exploratory activities, extraction (mostly open ...
Phosphate Minerals in Meteorites and Lunar Rocks ...
Phosphorus is in meteorites and lunar rocks a minor, but in many respects important element. It occurs chemically bound as phosphates and phosphides, and it occurs in solid solution in the ironnickel alloys kamacite and taenite. Broadly speaking, the phosphates are characteristic of the stone meteorites and of the inclusionrich parts of the ...
Phosphorus – CHEMISTRY
· Phosphate rock, which usually contains calcium phosphate, was first used in 1850 to make phosphorus, and following the introduction of the electric arc furnace in 1890, elemental phosphorus production switched from the boneash heating, to electric arc production from phosphate rock. After the depletion of world guano sources about the same time, mineral phosphates became .

Phosphate rock (or Phosphorite) basically refers to any form of rock that possesses a high phosphorous content. Often extracted by means of surface drilling, this rock is mined through a blasting and harvesting process. Its uses are quite varied. Frequently it is utilized to make calcium phosphate nutritional supplements, and more regularly it is put into fertilizers for agricultural use.

Abstract. 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. Nonetheless, in common igneous and metamorphic rocks phosphate mineral ...
Phosphate Mining: an Unsustainable Business | AEFJN
· The phosphate rock mining industry is concentrated in a few countries and is subject to geopolitical dynamics. The phosphate derived from the rock is a key ingredient in chemical fertilizers used in industrial agriculture. Therefore the industry claims that securing a reliable supply of phosphate rocks is essential to food security. However, our study demonstrates that phosphate rock ...
INDUSTRIAL MINERALS: PHOSPHATE
· Phosphate rock, which is partially made of apatite (an impure tricalcium phosphate mineral), is an important commercial source of this element. About 50 percent of the global phosphorus reserves are in the Arab nations. Large deposits of apatite are loed in China, Russia, Morocco, Florida, Idaho, Tennessee, Utah, and elsewhere. Albright and Wilson in the United Kingdom and their Niagara ...
AVAILABILITY OF MINERAL PHOSPHATES FOR PLANT NUTRITION
· rock phosphate by composting the mineral with cow and horse manure. Tottingham and Hoffmann (26), following the same line of investigation as that which McDowell observed, actually found a decrease in water soluble phosphorus, but the results were similar with acid phosphate. Krober (12) was unable to find any increase in availability of mineral phosphates by composting with sawdust .

Phosphate rock is an imprecise term that describes naturally occurring geologic materials (minerals) that contain a relatively high concentration of P. The term PR is used to describe raw (unbenefi ciated) phosphate ores, but may also be applied to benefi ciated or concentrated products. Phosphate rock occurs in both sedimentary and igneous deposits across the world (Figure 1). Most (80 ...

Apatite: Its uses as a mineral and gemstone
Phosphate rock and phosphorite are names used for sedimentary rocks that contain at least 15% to 20% phosphate on the basis of weight. The phosphorous content in these rocks is mainly derived from the presence of apatite minerals. Determining which apatitegroup minerals are contained in the rock cannot be determined without laboratory testing because their particle sizes are so small ...
