Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
ANFO (/ ˈ æ n f oʊ / AN-foh) [1] (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial high explosive. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3 ) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO). [ 2 ]
Prilled is a term used in mining and manufacturing to refer to a product that has been pelletized. ANFO explosive typically comprises ammonium nitrate prills mixed with #2 fuel oil . [ 2 ] The pellets are a neater, simpler form for handling, with reduced dust.
Nitrogen fertilizers and synthetic products, such as urea and ammonium nitrate, are mainstays of industrial agriculture, and are essential to the nourishment of at least two billion people. [10] [13] Industrial facilities using the Haber process and its analogues have a significant ecological impact. Half of the nitrogen in the great quantities ...
In response to changes in mining technology, the product line expanded to include blasting agents based on ammonium nitrate and nitric acid in the 1940s. [7] Ammonium nitrate was produced from anhydrous ammonia and air (the DuPont process) beginning in the 1950s. [7] The original nitroglycerine-based products were phased out by 1983. [2]
The types of explosives manufactured includes ammonium nitrate, dynamite, electric, non electric and electronic detonators, detonating cord and cast boosters. They also produce surface and underground loading systems. [6] In 2012 Dyno Nobel had over a million tons of ammonium nitrate capacity and over 30 manufacturing facilities on two ...
Tovex is a 50/50 aqueous solution of ammonium nitrate and methylammonium nitrate (sometimes also called monomethylamine nitrate, or PR-M), sensitized fuels, and other ingredients including sodium nitrate prills, finely divided (paint-grade) aluminum, finely divided coal, proprietary materials to make some grades cap sensitive, and thickening agents to enhance water resistance and to act as ...
DFPCL is also a producer of Technical Ammonium Nitrate (TAN), which is used in the agricultural and chemical industries and as an explosive in the mining and infrastructure industries. [10] Until 2014, imports of TAN from Russia and Ukraine in loose form were high. [ 10 ]
