Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion , sinkholes , loss of biodiversity , or the contamination of soil , groundwater , and surface water by chemicals emitted from mining processes.
Once a mine closes, mining facilities that occupy a small area of the disturbed land can either be salvaged or town down. [13] The main visual and aesthetic impacts of mining are the open pits and waste rock disposal areas. Open-pit mining disturbs larger areas than underground mining making the visual impacts much greater. [13]
In this report, an assessment is made of the literature on metal flows and cycles in nature and in society, the way they are connected, and the potential impact related to them. The four areas of focus are 1) Local impacts of mining, 2) life cycle energy use, 3) non-metal sources, and 4) the need for a final sink.
For example, a paper presented in 1991 at a major international conference on this subject was titled: "The Prediction of Acid Rock Drainage – Lessons from the Database". [2] Both AMD and ARD refer to low pH or acidic waters caused by the oxidation of sulfide minerals , though ARD is the more generic name.
However, in-situ biomining also has the most environmental concerns of all of the leaching methods, as there is the potential for the contamination of ground water. [ 20 ] [ 21 ] These concerns however can be careful managed, especially because most of this mining would occur below the water table.

Last year, the World Bank approved a $73 million grant to help the Congolese government study the dam’s environmental and social impact. The dam, known as Inga III, would produce an enormous amount of energy in a country where there is almost none. But environmental experts say mining companies and aluminum smelters would be the main ...
Instead, it impacts the whole country as low wages for high-risk mining worsen poverty rates, exacerbating negative social impacts such as conflict, higher crime rates, and child mortality. The effects of the exploitation of natural resources in the local community of a developing country are also exhibited in the impacts from the Ok Tedi Mine .
