2021-1-20  Abstract Mining of iron ore is a highly capital- and energy-intensive process. Life cycle assessment (LCA) of the mining and mineral processing of iron ore in Australia was carried out in this chapter using SimaPro LCA software as a case study. The environmental impacts considered in the study were embodied energy and greenhouse gas (GHG) emissions, while the functional unit was 1 t of iron

Analysis of life-cycle GHG emissions for iron ore

In this study, a life-cycle model for mining and processing of Chinese iron ores is developed and used to estimate GHG emissions. Results show that the mean life-cycle GHG emissions for Chinese iron ore production are 270 kg CO 2 e/tonne, with a 90% confidence interval ranging from 210 to 380 kg CO 2

2019-5-1  The Life Cycle Impact Assessment results were produced for each year over the life of the project, generating insight about the relationships between ore composition, grade, processing method and environmental impacts. The environmental impacts vary significantly during the life of a project and a temporally explicit LCA can highlight these.

2017-7-18  Iron ore mining was the mainstay of the Liberian economy between 1960 and 1980, contributing more than 60% of export earnings and about 25% of GDP (Boakye et al. 2012), which then ranked Liberia as the largest exporter of iron in Africa and third largest in the world. Gold and diamond mining in Liberia was carried out largely by alluvial mining
