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.
How difficult is it to mine diamonds?
Generally, diamonds are found in greater number and quality in the ocean, but the mining process is more difficult. In order to mine the diamonds, the ocean floor must be dredged and the dirt is brought up to the mining ship where it is sifted for diamonds.
Marine diamond mining extracts diamonds from the ocean floor using special mining ships. Horizontal marine diamond mining uses a crawler to suck gravel from the ocean floor to the surface via flexible pipes, while vertical diamond mining uses a large, ship-mounted drill to pull up the diamond-bearing gravel.
