Energy and greenhouse gas impacts of mining and mineral processing

The embodied energy values were 153 MJ/t ore, 55 MJ/t ore and 8329 MJ/t concentrate for iron ore, bauxite and copper concentrate respectively. These results show that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.
