  • Open Pit Mining an overview ScienceDirect Topics

    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. Research needs include studies of slope stability, dewatering on a large scale, methods of placement of spent shale in the pit, and a plan for location

  • How can metal mining impact the environment?

    Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby. Waste piles from processing, such as tailings impoundments, leach piles, and slag piles
