  • 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.

  • The worlds deepest, biggest and deadliest open pit

    When underground mining became too costly in the 1950s, Berkeley Pit became an open pit mine. As the mine grew bigger and deeper, groundwater began to seep into the pit, and pumps had to be installed to keep it from slowly flooding.

    Open Pit Mining Common in the U.S., open pit mining involves removing ore (copper, gold, silver, uranium) and overburden, the valueless rock that overlies the ore. The open pit is wider at the top than at the bottom and the pit wall contains steps or benches that prevent rock from landsliding or falling to the bottom.

  • 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
