benchmarked the energy consumption of open cut iron ore and gold mines. In investigating iron ore in an open cut mine, it was reported that there was potential to reduce the mining costs (based on energy savings) by 36% and milling costs by 47%. For gold mining this estimate was reduced to a staggering 53% for milling. Examples of Energy Events

Iron and Steel – Analysis - IEA

Over the past decade, expanding steel production has raised total energy demand and CO 2 emissions in the subsector. Substantial cuts in energy demand and CO 2 emissions will therefore be needed by 2030 to get on track with the Net Zero Emissions by 2050 Scenario.. Short-term CO 2 emissions reductions can be achieved largely through energy efficiency improvements and increased scrap collection ...
