Increases in the demand for iron lead to the mining of iron ores with lower iron contents, which increases the generation of tailings. Consequently, disposal of IOTs Over the years, the impact of mining on the economy, environment, and society has attracted several views (Balasubramanian, 2017; Festin et al., 2018; Mensah Evaluating the environmental and economic impact of 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 extraction and production. The improper disposal of such waste causes negative impact on the environment. Environmental effects on soil due to IOT are commonly connected to soil Except for bauxite, iron and manganese, which are listed as ores (gross weight), metal production is reported as metal content (net weight). In order to construct a homogeneous measure of extracted crude ore that is used as an input from the natural environment to the economic system, we applied country- and commodity-specific Surge in global metal mining threatens vulnerable ecosystems

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 2-31. Introduction . Concrete is a raw material often utilized in construction and serves as the foundation for all infrastructure projects and construction projects worldwide [1,2,3,4,5].Depending on the kind of concrete and the quantity of cement used, the main components of concrete (cement) have diverse effects on the environment.Concrete Made with Iron Ore Tailings as a Fine Aggregate: A

All these different effects add up to serious on-site habitat damage. Mining also creates knock-on effects — like water pollution, air pollution and vegetation loss as a result of soil eruption. This can lead to greater habitat loss beyond the immediate location.

Over the years, mining and metallurgical activities have rapidly influenced the human population. The manufacturing process of manganese (Mn) compounds and their use in industries increased the negative effect on the environment. Therefore, the recovery process of Mn from metal-containing wastes has become very crucial.The questionnaire consisted of both open and closed ended questions. Aspects covered in the questionnaires were socioeconomic characteristics of the respondents, effects of rutile, iron ore and diamond mining on vegetation and land, and types of restoration measures and their effectiveness in improving environmental Environmental Impacts: Local Perspectives of Selected Mining

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.The environmental damage associated with mining is well-known, in terms of land clearing, ecosystem degradation, or water pollution.

Mining operations degrade natural ecosystems by generating a large quantity of mine tailings. Mine tailings remain in dams/open ponds without further treatment after valuable metals such as iron ore have been extracted. Therefore, rehabilitation of tailings to mitigate the negative environmental impacts is of the utmost necessity. This The state of Goa covers an area of only 0.11 % of India (Bhushan and Hazra 2008), but 18 % of iron ore comes from this state (IMYB 2010) accounting for 5 million tonnes/month (USGS 2013).(PDF) Impact of Mining on Environment in Goa: a review
