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
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.
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.
How Are Diamonds Mined And Processed. How Are Diamonds Mined And Processed. ... Thanks for helping out in my science report. I needed info on how are diamonds extracted from kimberlite and the open pit mining process was really useful. What''s ur last name? i''m doing a project and i''m trying to cite u.

Diamond mining process. 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 d. remove; How are diamonds mined a look at the global supply
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 ...
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.

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.
Openpit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, openpit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used.
