  • The Mining Process Waihi Gold

    1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from

  • Bingham Canyon Mine, Utah NASA

    The Bingham Canyon Mine is one of the largest openpit mines in the world, measuring over 4 kilometers wide and 1,200 meters deep. Mining first began in Bingham Canyon in the late nineteenth century, when shafts were sunk to remove gold, silver, and lead deposits that played out by the early 1900s. It would take the advent of openpit mining in 1899 to turn the Bingham copper deposit into

  • Surface Mining Techniques used in the Oil Sands Oil

    Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as openpit, opencut or opencast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.

  • Environmental Risks of Mining

    Open pit 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.
