Abstract. Mine tailings—the residue remaining after mineral processing—represent a serious risk to the natural environment, and the failure of tailing storage facilities has caused some of the ...
The world faces two energy problems: most of our energy still produces greenhouse gas emissions, and hundreds of millions lack access to energy. The world lacks safe, low-carbon, and cheap large-scale energy alternatives to fossil fuels. Until we scale up those alternatives the world will continue to face the two energy problems of …
Mining and mineral-processing wastes—the solid and liquid materials generated after mining and ore processing at or near mine sites ()—have no current economic use.A number of environmental problems are associated with the disposal of this waste, including contamination of streams and lakes and pronounced landscape …
As a result, old, unneeded metal items may be gathered and converted into whole new ones with no need for mining. Like any other rising business, metal recycling faces all its set of obstacles. Even with awareness of climate change and widespread consensus on environmental conservation, an inadequate number of items wind up in recycling centers.
Water treatment processes, waste disposal, and rehabilitation of mining areas are some of the highlighted challenge areas. The industry produces valuable waste streams that could be recycled and reused more effectively, such as truck tyres and plastic waste. Gaps in working capital is one of the challenges faced by local suppliers. Joint

A 2017 study found that waste from chromium mining in Odisha polluted local water sources, highlighting the dangers of mining by-products. The report found that levels of chromium, which is toxic to humans, in local water sources reached up to 1.46mg/L, orders of magnitude above the limit of 0.05mg/L considered safe by the …
One cause of mining is population growth. With an increasing population, the overall world consumption levels also increase. This means that in order to be able to provide enough goods for the world population, resources have to be extracted at large scale. One great possibility to extract these resources is mining.
