  • Underground mining block caving, bore hole, drift

    TechnologyAdvantagesTypesSummaryUnderground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in. The mining company selects the best feasible way to get the minerals extracted out.在greatmining上查看更多信息
  • The Mining Process Waihi Gold

    A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

  • Underground Mining Methods — New Pacific Metals

    Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
