Green Mining

Green Mining

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).
