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 …

Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.
