Phosphate Wikipedia

2021-4-14  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

Phosphorite Wikipedia

2021-4-13  Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through

The story of phosphorus: Global food security and

2009-5-1  Plants require phosphorus to grow. Phosphorus is an element on the periodic table that cannot be substituted and is therefore vital for producing the food we eat (Steen, 1998).90% of global demand for phosphorus is for food production, currently around 148 million tonnes of phosphate rock per year (Smil, 2000a, Smil, 2000b, Gunther, 2005).. The demand for phosphorus is predicted to increase

What Is Involved in Phosphate Mining? (with pictures)

2021-2-11  Phosphate mining is an important part of the process of producing chemical fertilizers. The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are located. Most phosphate mining is conducted as open-pit mining rather than subsurface mining.

Calcium phosphate Ca3(PO4)2 PubChem

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract.

Fertiliser — Science Learning Hub

Superphosphate was developed to address the shortage of phosphorus in soil. It is made by reacting finely ground phosphate rock with sulfuric acid. In this form, phosphate is rapidly released into the soil, where it can be used by plants. Superphosphate manufacture began in New Zealand in 1882, and over 3 million tonnes are produced annually.

Examples of Renewable and Non-Renewable

#9 Phosphate rock. As the name suggests, phosphate rock is the main source of phosphorus. Phosphorus is the key nutrient in agriculture. Without phosphorus, plants simply cannot grow, as this essential nutrient promotes root formation, seed development, and

Nitrogen, Phosphate & Potash for Plants Home

Nitrogen, Phosphate & Potash for Plants. The proper balance of certain elements in soil can make or break a garden. Nitrogen, phosphate and potash, naturally occurring elements, are required for

Phosphorus (P) Chemical properties, Health and

Phosphate is a dietary requirement, the recommended intake is 800 mg/day, a normal diet provides between 1000 and 2000 mg/day, depending on the extent to which phosphate rich foods are consumed. Humans have changed the natural phosphate supply radically by addition of phosphate-rich manures to the soil and by the use of phosphate-containing

Rock and Mineral Uses from Rockman

2020-11-1  Phosphate Phosphate rock is used to produce phosphoric acid for ammoniated phosphate fertilizers, feed additives for livestock, elemental phosphorus, and a variety of phosphate chemicals for industrial and home consumers. Phosphoric acid also helps provide the "tingly" taste you experience when drinking many soft drinks.

Harnessing Peptide Binding to Capture and Reclaim

2021-3-16  However, natural P resources (phosphate rock) are depleting. The authors describe the current situation and a forecast for future phosphate prodn. and reserves. The current depletion of phosphate reserves and the increasingly stringent discharge regulations have led to the development of various P-recovery techniques from wastewater.

Fertilizer Wikipedia

2021-4-22  Phosphate fertilizers are obtained by extraction from phosphate rock, which contains two principal phosphorus-containing minerals, fluorapatite Ca 5 (PO 4) 3 F (CFA) and hydroxyapatite Ca 5 (PO 4) 3 OH. These minerals are converted into water-soluble phosphate salts by treatment with sulfuric (H 2 SO 4) or phosphoric acids (H 3 PO 4).The large production of sulfuric acid is primarily motivated

Comparing Fertilizer Materials — Pennsylvania

Materials such as raw rock phosphate have a very low water solubility. Particle size of a fertilizer material can be important for both agronomic and handling reasons. Agronomically, particle size is most important for the sparingly soluble materials such as rock phosphate. These materials must be very finely ground to ensure sufficient solubility.
