The radioactive content of the fertilizers varies considerably and depends both on their concentrations in the parent mineral and on the fertilizer production process. Uranium-238 concentrations can range from 7 to 100 pCi/g in phosphate rock and from 1 to 67 pCi/g in phosphate fertilizers.
The two commercial forms of orthophosphates are monoammonium phosphate (MAP) and diammonium phosphate (DAP). Polyphosphate fertilizers contain a variety of polymeric forms mixed with some orthophosphate. Present production capacities for manufacturing ammonium phosphate fertilizers are given and future capacities are projected. The methods and
The source of nitrogen fertilizers is acheived through the synthesis of ammonia through the Haber-Bosch Process (which entails converting atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures). The bulk of the industry’s energy demand lies approximately at about 87% for the production of ammonia: To produce
Phosphate rock (phosphorite) mining is the fifth largest mining industry in the United States in terms of quantity of material mined. In 1989 the total production of phosphate rock in the U.S. was estimated at 38 million metric tons (MT). Most phosphate production leads to the making of fertilizers.
Wet process is by far the most common route and the acid can be used in phosphate fertilizers production (DAP, MAP, SPA). Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals, pharmaceuticals, detergents, stone products, and other nonfertilizer products. The last method, using a rotary

The fertilizer resources and production play a pivotal role for the economic growth of agriculture-based countries like India. About 35-40% of the requirement of raw material for phosphatic fertilizer production is met through indigenous sources. The rest is imported in the form of rock-phosphate, phosphoric acid and direct fertilizers. The

Phosphatic fertilizers are of great demand during recent times and the demand is increasing steadily. BARC has developed a process for development of Phosphorus fertilizer formulation from bio-sludge. Chemically synthesized phosphatic fertilizers have limitations in term of availability and they are effective at certain levels. On the contrary
Phosphate rock is the basic material used in all phosphorus fertilizer production. The most important deposits are sedimentary materials, laid down in beds under the ocean and later lifted up into land masses. Other sources are igneous, created when phosphate rich lava solidifies into rock. Almost all phosphate rock is strip mined. It typically

The PhosEnergy Process: A proven and patented technology, the PhosEnergy Process was developed to recover uranium from phosphate fertilizer production. Current estimates indicate that more than US$1 billion per annum of uranium goes unrecovered worldwide in the manufacture of phosphate fertilizers.
Rock phosphate deposits contain many million tonnes of uranium, which may be extracted as a by-product of making fertilisers. Some 20,000 tonnes of uranium has already been obtained from these rock phosphate deposits, but the process became uneconomic in the 1990s. Higher uranium prices and process refinements have changed the economic situation.

2.1 Raw Materials for Phosphoric Acid Production Bones used to be the principal natural source of phosphorus but phosphoric acid today is produced from phosphatic ores mined in various parts of the world. Phosphate ores are of two major geological origins:-–
Diammonium phosphate (DAP) (chemical formula (NH 4) 2 HPO 4, IUPAC name diammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation:
The nitro phosphate process was developed by Erling Johansen in Norway in 1927/28 who named it as the ODDA process after the town of ODDA where it was developed. Another process for the production of nitrophosphates is the PEC process which refers to the French firm Potasse et Engrais Chimiques. Nirophosphate was first commercially produced in
