Open Pit Mining Methods

To safely open pit mine the kimberlite, water retention structures dikes were constructed in the lake to hold back the lake waters during mining. The main cost advantage of open pit mining is that it allows mining with more efficient larger equipment. This means faster production and mining of lower grades of ore is possible. It also means

Diamond Mining Methods Diamondm Cape Town

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
