ammonia plant used in mining

Getting to the bottom of ammonia usage in

In practice ammonia is often used in the surface refrigeration plants due to its high COP and heat transfer, which offers significant reductions in operational costs. For example AngloGold Ashanti, one of the biggest mining corporations has installed ammonia refrigeration technology at its Mponeng gold mine in Gauteng in South Africa. In Poland, the JSW Group’s Borynia-Zofiówka-Jastrzębie coal mine also uses ammonia
