environmental impacts of iron ore

ABSTRACT 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 CO 2 emissions The EII considers the characteristics of the mineral (such as the quality size hardness iron ore grade reducibility mineral/waste rate Environmental impacts of mining can occur at local regional and global scales through direct and indirect mining practices Impacts can result in erosion sinkholes loss of biodiversity or the contamination of soil groundwater and surface water by the chemicals emitted from mining processes
