The Environmental Impact of Mining

· Open-Pit Mining. Open-pit mining, one of the most common forms, is one of the most damaging. Miners hollow out a section of land, digging down to create a workable area and extract valuable raw materials. This method leaves behind large pits in the earth and can contaminate the groundwater with chemicals used in the mining process. The land left behind, if not rehabilitated, is

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, 2022).

Surface Mining Techniques used in the Oil

· Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface.
