  • Analysis of lifecycle GHG emissions for iron ore mining

    · The largest GHG emissions source for open pit mining was iron ore loading and hauling (67% in total mining emissions), where diesel powered loaders and trucks are used to move ore from mine for further processing The second largest contributor is related to vegetation and soil removal, which includes GHG emissions from microbial decomposition of the removed biomass and soil andAlthough iron ore mines are remote, they still move with the times The world is changing Miners are beginning to reposition themselves for the future – for the next century of growth And they're not being shy about it This resolve is being tested more than ever, with some companies setting decarbonization targets in a push to lower emissions and stay at the forefront of global industryZero emission iron ore mining – WorleyIron ore and steel production are major sources for greenhouse gas (GHG) emissions Since China has committed to lowering carbon intensity to meet climate change mitigation goals, detailed studies of the energy use and GHG emissions associated with iron ore mining and processing can aid in quantifying the impact and effectiveness of emissions reduction strategies In this study, a lifecycleAnalysis of lifecycle GHG emissions for iron ore mining
