ANFO (/ ˈænfoʊ / 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]

ANFO provides excellent heave energy compared with explosives that contain a high emulsion content. ANFO is a dry and free flowing product, allowing delivery by loose pour or pneumatic loading.

Ammonium nitrate-fuel oil mixture is commercially available as pale white, gray, yellow, or pink oil-covered prills with a petroleum odor. Non-commercially produced forms may be darker in color. It is used for blasting rock and in some types of mining. It will accelerate the burning of combustible materials. The ammonium nitrate is soluble in water. If large quantities of this material are ...
