The mining process allows these acid and heavy metal generating reactions to occur at much higher rates than occur in nature. Metals mining produces waste rock and mine tailings with a surface area that is vastly greater than the undisturbed rock. Extracting valuable metals from ore usually involves crushing the ore rock into a mud slurry
communities have been particularly exposed to the detrimental effects of contamination arising from mining and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left thousands of sites in Africa contaminated by mining and associated mine dumps such as tailings and slag material.
Apr 15, 2015 · Underground mining, by its nature, presents a range of health and safety hazards that are different from those in other sectors. Some hazards, such as ground instability, are inherent in the underground environment.
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.

Lead and Mercury Emissions from Mining. Global releases of lead from smelting and refining nonferrous metals (e.g. gold, lead, zinc, copper) total over 28,000 metric tons/year. 1 Global releases of mercury from smelting and refining nonferrous metals total 710 metric tons/year –
With all of these possible mining processes, however, there are high costs and disputes over who would harvest and profit from these resources. Some scientists believe that mining on the seabed could cause less environmental impacts than mining on land. There could also be harmful effects on seabed ecosystems and organisms, however.
Some of the major effects of mining on the environment are as follows: Minerals are the natural resources which play an important role in the economic development of the country. But the extraction and mining of these natural resources leads to some adverse effect on our environment as well.
