Mine closure is the final step in the mining cycle. Mining eventually depletes the metalrich material that could be economically removed at a specific mine. When mining can no longer be profitably conducted, the mine and related facilities used in beneficiation or smelting will be closed.

In an openpit mine or quarry, a drone survey refers to the use of a drone (or UAV – unmanned aerial vehicle) equipped with a downwardfacing RGB camera to capture images of a site from different vantage points. Out of these images, a photogrammetry software can recreate georeferenced 3D maps, contour lines digital terrain models or digital surface models of the mining site.

Mining operations, however expansive and complex, are temporary. Eventually, once the most accessible and valuable materials have been extracted, the mine is closed, and the site must be restored back to its original state.

The result of all this is barren land that stays contaminated long after a coal mine shuts down. Although many countries require reclamation plans for coal mining sites, undoing all the environmental damages to water supplies, destroyed habitats, and poor air quality is a long and problematic task. This land disturbance is on a vast scale.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have

· Mining alters the natural landscape and discharges large volumes of wastes that pose serious pollution hazards to the environment, to human health and to agriculture. As a result, the recent 2 decades have witnessed a global surge in research on postmining landscape restoration, yielding a suite of techniques including physical, chemical, biological (also known as phytoremediation) and

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

The environmental risks mining presents to land, water, biodiversity and people can be difficult to foresee but have the potential to last long after the mine has closed. The loss of valuable water and land assets affected by mining are highly significant to local communities and for long term sustainability.

· Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
WhatsApp In gold mining, two main processes, one based on mercury and the other based on cyanide, are used to aggregate gold dust after its segregation from the placer deposit or from the ore‐bearing rock. These processes are very toxic to the artisanal community and to the environment, in particular, to rivers where all the chemical waste is dumped ( Amazon River).
