Ammonium nitrate prills are industrial grade and specifically designed to be used as a solid oxidizer ingredient for explosive compositions such as anfo, wr anfo, heavy anfo emulsion and watergels. They are small-sized, low-moisture content, non-setting, porous spheres (prills) which are a lower density than agricultural grade ammonium nitrate used for fertilizer. The particle density of the prills is such that, when liquid fuel is properly applied to and mixed with them, the prills absorb the fuel uniformly which enhances reactivity. Ammonium nitrate is infinitely soluble in water and does not precipitate with any common chemical.

In recent years the emulsion explosives have had a large increase in the usage on surface and underground mines. The reason for this are the great advantages that emulsion explosives offer compared to other types of explosives on the market. The advantages of emulsion explosive include safety and security, excellent resistance to water, increased velocity of detonation, transport, handling and storage, savings in drilling operations and low gas emissions
