Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H 2 PO 4-, derived from phosphoric acid, H 3 PO 4.The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid.
Phosphate rock is the main source of phosphorous which is essential to all forms of life. It is a key component of DNA, it is used in the control of energy transfer and storage at the cellular level as well as playing an important role in metabolic processes.
The orthophosphate concentration in the ocean varies greatly from place to place and also with depth and time of day. Surface waters are greatly depleted in phosphate relative to deeper waters, due to biological activities that sequester phosphate in organisms.
Food production is fundamental to our existence, yet we are using up the world's supply of phosphorus, a critical ingredient in growing food. Today, phosphorus is mostly obtained from mined rock phosphate and is often combined in mineral fertilizers with sulphuric acid, nitrogen, and potassium.
Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding fluxes, air purifying agents, and hydrogen isotopes.
Asian Journal of Science and Technology (AJST) is a monthly, open access, peer-reviewed and fully refereed international journal. Being an international journal focused on Engineering, Management, Science and Mathematics, we broadly cover research work on next generation cutting edge technologies and effective marketing strategies.
MPC is a joint venture with Saudi Basic Industries Corporation and represents a USD 5.6 billion (nearly SAR 21 billion) investment, operating at two primary sites: Al Jalamid in northern Saudi Arabia, home to our phosphate mine and beneficiation plant; and the Eastern Province's Ras Al Khair, where our integrated chemical and fertilizer facility is based.
Effluent Guidelines are national standards for industrial wastewater discharges to surface waters and publicly owned treatment works (municipal sewage treatment plants). We issue Effluent Guidelines for categories of existing sources and new sources under Title III of the Clean Water Act. The ...
Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose.It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into blood during digestion.
