How Are Diamonds Mined And Extracted From the Ground

In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the post-processing is shorter and is a less resource-consuming task as diamonds are identified in situ of the work area. Offshore Marine Diamond Mining.

Deposits of,Open-pit mining - Wikipedia,Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or thePetra Diamonds | How are diamonds mined by Petra?,Mining of a diamond-bearing kimberlite generally starts with the excavation of a pit into the kimberlite pipe. In this process, called ‘‘open-pit’’ or ‘‘open-cast’’ mining, the initially weathered ore material is removed with large hydraulic shovels and ore trucks. Hard rock is drilled and blasted with explosives so the broken material can be removed.

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 approximately 45,000 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.
