The Enviormental Impact Of Open Pit Mining

Environmental risks of mining,Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

The impacts are more for open-pit mines than for underground mines, which tend to produce less waste. Deterioration of aquatic ecosystems and receiving water bodies, often involves reductions in water quality, can be among the most severe potential impacts of mining. Mining and the processing of minerals have a profound impact on our environment.Jan 17, 2021 What is Strip Mining? Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the ‘overburden’) are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels.

Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).There are more than 50 years of the copper surface mining in Majdanpek, Serbia. During this period, the impact of mining activities on the environment was multifaceted: degradation of the land - mostly forests, air pollution, water and soil and others.
