2020-6-29Uses of phosphoric acid. About 90 of the phosphoric acid produced is used to make fertiliers. It is mainly converted into three phosphate salts which are used as fertiliers. They are triple superphosphate TSP diamonium hydrogenphosphate DAP and monoammonium dihydrogenphosphate MAP.
Use of nitrogen- and phosphorus-based synthetic fertiliers shows an increasing trend but this has led to large-scale influx of reactive nitrogen in the environment with serious implications on human health and the environment. On the other hand phosphorus a non-renewable resource faces a serious risk of depletion.
The products are stored on-site until they can be delivered to various markets such as gas stations airports and chemical plants.
2020-6-17Potash is the common name given to a group of minerals containing potassium that are typically used in agriculture to help plants grow. The most common type of potash is potassium chloride KCl.
Industrial inorganic chemistry includes subdivisions of the chemical industry that manufacture inorganic products on a large scale such as the heavy inorganics chlor-alkalis sulfuric acid sulfates and fertiliers potassium nitrogen and phosphorus products as well as segments of fine chemicals that are used to produce high purity inorganics on a much smaller scale.
Biochemistry studies the molecules and chemical reactions in organisms trying to understand the nature of life at the molecular level. .
This form of mining uses water-jet cutting systems and downhole slurry pumps to extract subsurface minerals through a single borehole drilled from and up to the surface for further treatment .
Uses. Copper sulphate is a very versatile chemical with as extensive a range of uses in industry as it has in agriculture. Its principal employment is in agriculture and up to a generation or so ago about its only uses in industry were as a mordant for dyeing and for electroplating.
Surface mining open pit mining This type of mining takes place from the surface of the Earth. In open pit mining the topsoil is removed first and placed on the side of a trench. Then the surface layers of rock are removed to expose the deeper valuable mineral layers.

The first process is included in the general category of chemical precipitation processes. Phosphorous is removed with 90 efficiency and the final P concentration is lower than 0.5 mgl.
Chemically bonded phosphate ceramics have made an excellent progress in the last 10 years and are poised to be one of the major inorganic room-temperature setting materials for nuclear structural dental and prosthetic applications.
2020-3-6Pyrophosphoric acid also known as diphosphoric acid is the inorganic compound with the formula H 4 P 2 O 7 or more descriptively HO 2 PO 2 O. Colorless and odorless it is soluble in water diethyl ether and ethyl alcohol. The anhydrous acid crystallies in two polymorphs which melt at 54.3 C and 71.5 C.
Chemical processes used in phosphate mining. useful mining chemical processes uses of phosphate. chemical processes used in phosphate mining.
2011-10-15Smaller volumes of phosphate esters are consumed in other industrial processes as antifoam agents TBP solvents in chemical manufacturing TOP and processing of uranium and other rare earth metal TBP 29 and as a leveling agent in floor finishes.
Phosphate fertiliation of soils has always been important. Vast areas of agricultural land can be poor if the soil has a phosphate P deficiency.
Chemistry is the science of matter and the changes it undergoes during chemical reactions.
The first treatise on mining and extractive metallurgy published by Georgius Agricola in 1556 was also the first to highlight the destructive environmental side effects of mining and metals extraction namely dead fish and poisoned water. These effects unfortunately are still with us.
Phosphate remobilisation rates increased significantly yields doubled and recovered PO 4 3 concentrations increased four times using a task specific bio-electric system.

2015-10-1Chemical properties Edit FilePhosphate Group.svg. The phosphate ion is a polyatomic ion with the empirical formula PO 4 3 and a molar mass of 94.97 gmol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement.
2018-12-5A phosphate PO34 is an inorganic chemical and a salt of phosphoric acid. In organic chemistry a phosphate or organophosphate is an ester of phosphoric acid. Of the various phosphoric acids and phosphates organic phosphates are important in biochemistry and biogeochemistry ecology and inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry.
1. Introduction. Phosphate rocks of sedimentary origin contain Uranium 238 U Thorium 232 Th and its decay products in addition to phosphate minerals Roesseler 1990.
2020-6-29Phosphate rock cannot be used as a fertiliser because it is insoluble but it can be used to make fertilisers. Phosphate rock contains phosphorus compounds.
