Mining activities produce carbon dioxide. Trucks and other vehicles give off exhaust gases. If the mining process is not monitored properly acid and other chemicals from chemical processing can run into nearby water systems such as rivers. This is poisonous to animals and plants as well as to humans who may rely on that water for drinking.

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the
