Abstract
DE LA TORRE DE PALACIOS, LUIS. NATURAL RESOURCES SUSTAINABILITY: IRON ORE MINING. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.170, pp.227-234. ISSN 0012-7353.
In the present article, a new tool to determine environmental sustainability, the energy impact index (EII) was developed to classify different iron mine projects according to two main parameters including energy consumption and CO2 emissions. The EII considers the characteristics of the mineral (such as the quality, size, hardness, iron ore grade, reducibility, mineral/waste rate, and type of deposit), mining processes (type of exploitation, ore processing, available technology), and transportation (distance to cover).
Keywords : Sustainability; iron; energy; CO2 emissions.
