Bulk Explosives

Ammonium Nitrate

Basic materials of AN are Ammonia and Nitric Acid (NA) which react in a pipe reactor producing Ammonium Nitrate with concentration of ± 85%.


  • Water content maximum 0.25 %
  • Oil absorption > 6%
  • Bulk Density 0.73 0.78 Kg /dm3
  • Nitrogen content minimum 34.5 %.
  • Purity 99.55% (weigh).

Ammonium Nitrate Fuel Oil (ANFO)

Ammonium Nitrate Fuel Oil (ANFO) is one of many explosive raw material types in which its biggest components consist of AN mixed with fuel oil.

Based on the research studies, it is found that the experts in mining tend to use ANFO for its safe and economic characteristics.

Compared to other explosive raw materials, ANFO is categorized as dry-based and highly safe explosion both in underground explosion and in an open explosion with 1 to 12 inches or more diameters.


Emulsion is an explosive material made from liquid phase oxide mixed with oil phase (diesel or diesel oil) added by emulsifier to stabilize the emulsion phase. Glass micro-balloons or chemical gassing agent is used for spreading agent in order to create a hot spot atmosphere because the granular oxidizing is very small, which is about 0.001 mm.

Currently, the using of explosive emulsion is going wider in various mineral mining, either in cartridge or in a Mobile Mixer Unit (MMU) truck to the explosion hole.

MNK has multiple on-site emulsion plants with several customers in Kalimantan and Sulawesi and we are continuously expanding every year.
