As the severe damage of phosphate enrichment in the water ecosystem and the supply shortage of phosphate rock, developing an efficient method for the removal and recycling of phosphate from wastewater is of great significance. To achieve this goal, adsorption technology has been widely investigated, and various adsorbents were developed.

Proponents of the theory argue that, due to the finite nature of resources and the increasing nature of demand, the important prediction is not when the world will run out of supply completely, but rather when it will run out of high-grade, easily-acquirable phosphate rock (Schroeder et …

JPMC currently operates three mines in Jordan producing phosphate rock, with a fourth mine at Al-Ruseifa having ceased production in 1985, and a downstream fertilizer and chemicals plant at Aqaba in the south of Jordan producing phosphoric acid, diammonium phosphate ("DAP"), sulphuric acid and Aluminum fluoride.

The main phosphate rock deposits are either sedimentary or igneous, each with different mineralogical, structural, and chemical properties (Van Enk et al., 2011). Marine sedimentary deposits account for 80% of the global phosphate rock production, with large producers such as China, Morocco, U.S. and Tunisia.

In the disclosed process of manufacturing phosphate fertilizer, a mixture of crushed phosphate rock, water and a catalyst in the form of a water-soluble metal salt of a transition metal is prepared. The pH value of the mixture is adjusted to the alkaline range and the mixture is permitted hydrolytically to degrade until a phosphate fertilizer of a high A.P.A. value is obtained.

In some low-grade phosphate rock mines, the content of Fe and Al is even higher than that of P 2 O 5, and it is usual that the P 2 O 5 content in phosphate rock is less than the Si and Ca content. In addition, some elements that are very rare in the Earth's crust are found to be relatively abundant ( Fig. 1) in phosphate rocks [ 17 ]. 7.1.

take (Cordell et al. 2011). Phosphate rock application as fertilizer is known a long time ago. Phosphate rock is relatively slow to re-lease soluble P, yet its low price appears to be very at-tractive as a phosphate fertilizer in comparison to the industrial P fertilizers. In Egypt, Qena Governorate, Deshna, and surrounding villages, farmers ...

In the phosphate industry, the phosphate content of the rock is usually expressed as tricalcium phosphate and traditionally referred to as bone phosphate of lime (P 2 O 5 × 2.1853 = BPL). The latter term is reminiscent of the time when bones were the principal source of phosphate in the fertilizer industry.

Based on these concerns, Bashan et al. (2013a, b) recommended that depending on soil pH, rather than sole tricalcium phosphate, a combination of multiple metal-P compounds, with addition of phosphate rock, and with or without tricalcium phosphate, should be used together or in tandem as an initial selection factor.

Curcao Island phosphate is a raw rock phosphate, naturally low in flourine, which is mined and ground without further processing. It has a similar P availability to dicalcium phosphate in cattle but not in sheep ( Ammerman et al., 1957 ). Mexican rock phosphate also contains P in a highly available form ( Webb et al., 1975 ).

Phosphate rocks that have been discovered in Akashat area/ Anbar Governorate, provided the basis to establish the phosphate fertilizers industry …

Tao et al. studied the effect of an oxidant (H 2 O 2) and a catalyst (MnO 2) on the leaching rate of phosphate rock and found that using H 2 O 2 as an oxidant for the catalysis of MnO 2 could enhance the removal rate of organic matter and strengthen the leaching rate of phosphate rock. Avdalović et al. found that iron-oxidizing ...

Misr Phosphate is one of the major companies producing phosphate rock concentrate in Egypt with production capacity of around 5 Million Tons a year from one of the biggest reserves in the world "Abu Tartour" located 50KM west of the city of El Kharga City, the capital of the New Valley Governate in the southwestern Egypt.

In some low-grade phosphate rock mines, the content of Fe and Al is even higher than that of P 2 O 5, and it is usual that the P 2 O 5 content in phosphate rock is less than the Si and Ca content. In addition, some elements …

US3632307A Process for the preparation of phosphoric. The acidulation of the phosphate rock with sulfuric acid to form phosphoric acid and calcium sulfate can be carried out in any possible way provided the conditions are such that calcium sulfate hemihydrate is formed The phosphate rock and the sulfuric acid are e g mixed at

From Al Jalamid, Concentrated Phosphate rock is transported by rail over 1,200 Km to Ras Al Khair Industrial City for processing at Ma'aden's Integrated Fertilizer Production Complex, which include Phosphoric Acid Plant, Sulfuric Acid Plant, Ammonia Plant, Di-Ammonium Phosphate, Granulation Plant and Desalination Plant.

Flotation of carbonate‐rich phosphate rock has been the subject of intensive research in recent years due to the depletion of deposits rich in silica. A flotation method called 'short conditioning' has been defined by the authors for the Al‐Jalamid rock.

The application of rock phosphates presents several advantages compared with the application of other phosphate fertilizers (Van Straaten, 2006; Hellal …

It can be seen from Table 1 that the P 2 O 5 content of phosphate tailings is 15.76%, the SiO 2 content is 22.49%, the MgO content is 3.42%, the CaO content is 34.68%, and the content of sesquioxide (Al 2 O 3 + Fe 2 O 3) is 2.28%.In addition, the heavy metal elements such as Pb and Cd in phosphate tailings were analyzed, and their contents were all relatively …

Phosphate rock reactivity is a measure of the rate of dissolution of phosphate rocks under standard laboratory conditions or in a given soil and under given field conditions (Rajan et al. 1996). The dissolution rate of phosphate rocks is mostly affected by soil properties and plant characters.

Phosphate rock deposits that are interesting for mining usually only occur under special conditions in some specific areas as a result of the phosphorus cycle (Filippelli 2011; Krauss et al., 1984). The main phosphate rock deposits are either sedimentary or igneous, each with different mineralogical, structural, and chemical properties (Van Enk ...
