How UltrAN® is produced at Yara
You can be sure of receiving quality products from Yara. Our production facilities supplying industries that manufacture civil explosives for quarries, mining and infrastructure works are ISO certified. Our Ammonium Nitrate processes are designed to ensure constant production of high-quality products.
How we make UltrAN
- Combine oxygen (from air) and ammonia to form nitric acid. This is done through several reactions (see grey boxes).
- Combine the nitric acid and ammonia to form an ammonium nitrate solution (see bright blue and orange boxes).
- Concentrate the ammonium nitrate solution, and further process to form droplets of crystallized ammonium nitrate. Dry and cool the solidified droplets, referred to as prills, to form the final product of UltrAN Technical Ammonium Nitrates (see dark grey below).
Products are optimised to suit various needs; for example, the components used in UltrAN Tropical are designed for tropical climates.
For ANFO, we produce quality porous prills designed to optimise high oil absorption and retention of fuel oil.
For emulsions, either ammonium nitrate solutions or uncoated high purity dense prills, free flowing quality.
