Phosphorus is the second most abundant mineral in the body, behind calcium. In your body it is primarily found in the form of phosphate. Every cell in your body needs phosphorus to function properly, but 85 percent of the phosphorus is stored in your bones. While phosphorus is an essential nutrient, getting too much can be bad for your health.
During the beneficiation of phosphate ores, huge amounts of oversize phosphate ores are rejected from crushers. This reject mostly contains low P 2 O 5 content and high gangue content. Phosphates are vital nonrenewable resources. The treatment of phosphate ore wastes of El-Nasr Mining Company, Sepaeya, Egypt aims to upgrade P >2O5 percent, adds a new …

The increasing concentration of available phosphorus allows plants to assimilate more nitrogen before the phosphorus is depleted. Thus, if sufficient phosphorus is available, elevated concentrations of nitrates will lead to algal blooms. Although levels of 0.08 to …
Activity concentration of 232 Th for Egypt, Nigeria, Tanzania, Brazil and South Africa is high compared to the other countries, while concentration of 40 K is higher for Egypt, Saudi Arabia, India, Italy, Pakistan and Nigeria than all other countries. This differentiation in results is because the mining and production of phosphate rocks are ...
Phosphate deposit of sedimentary origin contains higher concentration of 238U and its decay products than phosphate from volcanic or biological origin (Korkmaz & Turgut, 2005). The Egyptian phosphate is widely distributed in many local-ities on the Red Sea, Nile Valley (El-Sebaeya) and Western Desert ...

Phosphate rock fertilizer is contained in full vessels and containers and it is supplied in bulk quantities to various other countries of the world. Mining is the backbone of Egypt. There are many minerals that are found in Egypt. Coal, iron ore, tantalite and phosphate rock fertilizers in …
concentration, red blood count, white blood count and platelets count). This work can be considered as a step toward investigating natural radioactivity in phosphate hills in Egypt which is considered as the main part of radiological baseline map in Egypt. The experimental results will be used as guides for decision makers in solving some natural
The concentration of phosphate inside the cytosol is already greater than the concentration of phosphate in the surrounding fluid, yet, the cell still want to move more phosphate into the cell. To do this, energy is needed to move the phosphate ions against the concentration gradient, so the type of transportation requires is ACTIVE TRANSPORT.
The phosphate contains at least 15 to 20 percent of the phosphorite and this is the large enrichment over all the sedimentary rocks, which contains less than 0.2%. There are prime exporters and producers of the Rock phosphate fertilizer Egypt they have good producing ability. 2.
A shielded high purity germanium HPGe detector has been used to measure the natural concentration of 238U, 232Th, and 40K activities in the phosphate fertilizer and its components collected from Abu-Zaabal fertilizers and chemical industries in Egypt. The concentration ranges were 134.97-681.11 Bq kg(-1), 125.23-239.26 Bq kg(-1), and 446.11-882 ...
The relatively high concentration of Cu and Cr in well nos. 1 and 2 relative to well no. 3 can be attributed to the high concentration of these elements in the phosphate rocks (Table 5) which permit their leaching into the groundwater. The source rocks also …
Chemical properties. The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H

Creatine phosphate is the main high-energy, phosphate-storage molecule of muscle. In rested muscle, creatine phosphate is the predominant form (Demant and Rhodes, 1999 ); its maximal concentration is five times higher than that of ATP. During times of acute energy need, the creatine kinase (EC2.7.3.2) uses creatine phosphate for the ultrarapid ...
Phosphate rock (PR) is a general term that describes naturally occurring mineral assemblages containing a high concentration of phosphate minerals. The term refers to both unbeneficiated phosphate ores and concentrated products. Sedimentary deposits have provided about 80- 90 percent of world production in the last ten years.
