Can you take the heat? – Geothermal energy in mining [PDF]

, 2014
In 2013, there are less than 20 documented examples of operational geothermal systems on mine sites worldwide. This is surprising, since on remote mine sites, where fuels may have to be shipped in over great distances, heating and cooling from low ...
