the environmental impact of iron ore mining, in all its phases of, from excavation to beneficiation to transportation, may include detrimental effects on air quality, water quality, and biological species. · text under ccbysa licenseenvironment and geology effects of mining on environmentmining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash.any material that cannot be grown through agricultural processes, or created artificially in a laboratory ormba projects, projects mba, project report topics needmba projects, project mba, final project report topics mba/bba, training report, finance project reports, free sample hr project, marketing project, free mba projects writing, thesis, research projects, dissertation, synopsis complete mba/bba projects forappendix 2 environmental and social impacts of miningto fossil fuels, coal, and metal mining (matthews et al., 07). the amount of waste produced depends on the type of mineral extracted, as well as the size of the mine. g and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. by contrast, iron mining is less wasteful, with impact of technology on environmentpresent and possible adverse effects on the physical environment (1). it is undoubtedly true that twentyfirstcentury people are causing significant environmental changes, notably in theiron mountain an extraordinary and extreme environmenta century of active mining at iron mountain took an environmental toll. the first documented consequence of mining was fish kills in the sacramento river in 99, followed by severe air pollution from the openair heap roasting and smelters that
