Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by chemicals emitted from mining processes. These processes also affect the atmosphere through carbon emissions which contributes to climate changeIn iron ore mining, for example, most energy is required for hauling and loading, so diesel consumption is a major contributor to its GHG emissions.Transparency on greenhouse gas emissions from mining

Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its 1. Erosion. One of the effects of mining on the environment is erosion. The enormous Ok Tedi Mine in Papua New Guinea is a perfect example of how nearby areas can be significantly impacted by the erosion of exposed slopes, mine dumps, tailings dams, and the resulting siltation of drainages, creeks, and rivers.Top 9 Effects of Mining on the Environment Environment Go!

What effect does iron have on the environment? The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid change, erosion, air and water pollution and health hazards. Iron ore mining and processing of ore, affects the environment in myriad ways causing: (a) Land disturbance and change in land use pattern. (b) Affecting floral and faunal habitat. (c) Disturbing the natural watershed and drainage pattern of the area.GEO ENVIRONMENTAL IMPACT & ITS MANAGEMENT AT OPEN CAST IRON ORE

Surface mining has a significant effect on the environment, such as vegetation removal, removal of soil, sediment exposure, water erosion, reduction of biodiversity, and contamination of soil and water resources [1,2,3], thereby significantly disturbing ecosystems [].Establishment of vegetation is a critical step in achieving the Often the most significant environmental impact from mining activities are discharges of metals and other elements to soil as well as surface and ground water. The impact of discharges differs from element to element. For example, certain elements are essential to sustain life in low concentration, such as zinc (8-11mg/day for adults and 2-3Mines and environmental impact SGU

Mining in Western Australia has been dominated by a select group of commodities, initially gold in central WA from the 1890s, followed by the rise of iron ore, nickel, and bauxite–alumina in the 1950s–1960s. Other commodities have also made important contributions, such as mineral sands, diamonds, coal and base metals.Many of these commodities are found in critical forest landscapes, placing forests at increased risk as demand for minerals increases.

Iron ore tailings (IOT) represent a major problem in the mining industry worldwide due to large volumes of waste disposed in mine sites. IOT are exposed to the environment and subjected to wind and water dispersion, even under non-catastrophic scenarios as dam collapses, and the effects of these particles to the biota are still mostly unknown.The need for low-cost raw materials is driven by the fact that iron ore tailings, a prevalent kind of hazardous solid waste, have created major environmental issues. Although many studies have focused on using iron ore tailing (IOT) in concrete and have reported positive results, readers may find it difficult to accurately assess the Concrete Made with Iron Ore Tailings as a Fine Aggregate: A Step

In some countries, mining is responsible for significant amounts of water use, as well as water waste. Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air iron-ore mining and its tailing wastewaters usually show high levels of dissolved ions and particulate suspended matter, thus changing the water chemistry (Holopainen et al. 2003) and the bioavailability of metals.
