Gold Open Pit Mining Process

  1. Diamond Mining Methods

    Open-pit mining involves removing the layers of sand and rock found just above the kimberlite Once exposed the ore in the pit is broken up by blasting A single blast can break approx 3 000 tonnes of ore Once the ore is broken excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins The Kimberley Big Hole is an example of open-pit mining
