  • How Diamonds are mined Shimansky

    Open pit mining, such as the Kimberley Big Hole, involves removing the layers of sand and rock found just above the Kimberlite. The ore in the pit is then broken up by blasting. Once this ore is broken, it is loaded and then transported to a primary ore crusher where the diamond extractor process begins.
