Read MoreOpen-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 ...

When compared to underground mining methods, open pit surface mining is considerably more efficient. 1. Increased Efficiency. One of the biggest benefits open pit mining produces is the growth in the overall efficiency when compared to deep-shaft mining methods. Mining occurs on the surface, so there aren’t any space restrictions arising
