The process of diamond creation begins 100 miles underground where tremendous heat and pressure crystallize carbon into rough diamonds ... Openpit mining is only used when diamonds are near the ...
Openpit 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 ...

Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Figure 1. The Diavik diamond mine, shown here in February 2015, is located on a small island in Lac de Gras, approximately 300 km northeast of Yellowknife and 220 km south of the Arctic Circle, in a remote region of Canada''s Northwest Territories.
Mining We mine above ground, below ground, along the courses of ancient rivers, on coasts and under the sea, in four countries on two continents, always in partnership with our host communities. We work responsibly to make sure that, when diamonds are found, they play a central role in the community''s efforts to create jobs, improve education ...
The most commonly used form of extracting diamonds is described by the American Museum of Natural History as open pit or open cast mining. To begin this extraction technique a pit is created; it is dug with steep sides to create a cone narrowing to a point that is connected by roads built into large mines.
In the North, openpit mining comes with a unique set of challenges. For example, at the Diavik Diamond Mine, the diamond bearing orebodies, known as kimberlite pipes (volcanoes which brought diamonds to surface 55 million years ago), were under shallow waters of a large lake called Lac de Gras.

Kimberly diamond mine is an open pit and an underground mine based in Kimberley, South Africa. It has a width of 463 meters across and a depth of around 240 meters. There is a lot of infrastructure involved in digging mines and excavating diamonds.
Mining of a diamondbearing kimberlite generally starts with the excavation of a pit into the kimberlite pipe. In this process, called ''''openpit'''' or ''''opencast'''' mining, the initially weathered ore material is removed with large hydraulic shovels and ore trucks.
Open Pit Mining. Open Pit mining is a surface mining technique of extracting rock or minerals from the earth by removal from an open pit. It is used when diamond ore appears near the surface of is covered by a relatively thin layer of sand or gravel. Once the ore has been exposed, it is broken up before taking it to be processed.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
The Diavik Diamond Mine is located on a 20 square kilometre island, informally called East Island, in Lac de Gras, approximately 300 kilometres by air northeast of Yellowknife, capital of Canada''s Northwest Territories
Open pit mining is extracting diamond ores from solidified Kimberlite deposits, that are very close to the surface. This technique is used, when the underlying deposit is covered by a shallow layer of sand, gravel, or easily penetrable rock. A tunnel is drilled to access the deposit.
