Diamond Mining Methods Diamond Museum Cape Town

There are two types of pipe mining, namely open-pit mining and underground mining. 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, Crushers load the ore into haul trucks and transport it to a primary ore ...
