Mining operations also have lower greenhouse gas emissions due to better heat integration ...

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.

"Open-pit mining entails the removal of any overburden in order to expose the mineral deposit," the book says. "This operation is dependent on the type of overburden. In cases where the overburden consists of highly consolidated rock, blasting is used." Open-pit mining may cheaper when compared to other methods, but it is not environmentally-sound.
