Iron ore: energy, labor, and capital changes with technology.
Resource gathering is depending on leaner crude ores. Iron ore mining typifies this trend. To make lean taconite iron ores useful required a technologic breakthrough-pelletization. The shift to iron ore pellets has the advantage that they require less energy and labor per ton of molten iron than high-grade naturally concentrated ores. Increased reliance on pellets causes a geographic shift of s...
متن کاملUnder-mining health? Local impacts of iron ore mining in India
Environmental justice concerns about adverse impacts of extractive mining industries challenge their claim of broad-based development. However, empirical evidence of negative externalities attributable to mining enterprises is thin. In this paper, we examine the burden of Acute Respiratory Illness and Malaria among villagers along a gradient of proximity to mining areas to generate evidence per...
