Cooling the world’s deepest mine
Most mines use water as their primary cooling medium. The water is cooled in a refrigeration plant either on the surface or under ground and distributed to various parts of the mine. The major disadvantage of this is the distance of the plant from the rock face, which increases energy and cost requirement.
AngloGold use IDE’s transportable ice for mine cooling, so reducing by four times the required mass flow of the cooling system. This massively reduces energy consumption and costs.
