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.
The amount of energy required to mine and process iron ore is approximately 25% of energy required to extract and process aluminium ore. Thus, Iron ore has been mined for the past three thousand years by ancient and modern mankind. However, mining of iron ore has copious negative impacts on the environment.
extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. The impacts are often more
Many of iron ore mines have been abandoned due to environmental degradation and hazards in mining areas which causes a major concern. The technical reasons attributed for such abandonment being.
Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
The production of pig iron in blast furnaces was found to have the highest impact on greenhouse gas emissions and fossil fuel consumption, while the sintering process was with the highest impact on respiratory inorganics category. In this study, although all possible impact categories were covered, only product considered was cast steel.
Ore dust and gases released by the mining process are bad for the health of miners as well as the environment. Over time, exposure to the dust created by mining operations can lead to disease and buildup of scar tissue in the lungs.
