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.

Open Pit Mining Methods

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 limits of the ore pit to provide a bench, and the pit
