Iron Ore | ScienceDirect

The estimated GHG emissions were 11.9 kg CO 2 e for mining and processing 1 t of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total GHG emissions from the mining and processing of iron ore.
