Life cycle assessment of iron ore mining and

2015-1-1  Iron ore was chosen for this study due to the significant amount of this ore mined annually in Australia, as shown in Figure 20.2 over time. Since 2009, the production of iron ore from Australia has risen significantly. The percentage of global production and reserves for the major iron ore-producing countries for 2010 is shown in Figure 20.3

Iron Production Chemistry LibreTexts

2020-8-15  The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite (\(Fe_2O_3\)) but can also magnetite (\(Fe_3O_4\)), carbon called coke and limestone (\(CaCO_3\)). For the purpose of this discussion the iron ore oxide hematite (\(Fe_2O_3

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 e/tonne. The two largest contributors to
