Environmental Impacts Of Iron Ore Mining

8 The environmental impact of steel production. Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes. The major environmental impacts from integrated steel mills are from coking and iron-making.And or acid water seepage from coking coal and iron ore mining pits and mine waste pose environmental risks for surrounding soils and the groundwater. Coal mining additionally causes air pollution. Overall, the impacts of climatic changes are expected to aggravate or add to current environmental risks.Mining can become environmentally sustainable 1 by developing and integrating practices that reduce the environmental impact of mining operations. These practices include measures such as reducing water and energy consumption, minimizing land disturbance and waste production, preventing soil, water, and air pollution at mine sites, and conducting successful mine closure and reclamation.
