The Axora take on crushing and International Mining

 · The authors found that the average mine used 21 kWh per tonne of ore processed. Given diesel produces 270 g per kWh this means a plant produces 5.6 kg of CO2 per tonne of ore processed on average. For a 90 000 t/day site this might represent 510 t of CO2 per day (186 000 t/y) just for processing.
