  • What are the main methods of mining?

    There are four main mining methods: underground, open surface (pit), placer, and in-situ mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments In-situ mining.

  • Open Pit Mining

    Open-pit mining is probably most advanced because of developments in mining low-grade copper deposits and iron ore It is suitable for much of the resource if it is done on a large scale and will allow low-cost removal of most of the resource.

    Underground mines are the alternative to surface min Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers]Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
