Diamond Mines
Natural diamond sources have been discovered in approximately 35 different countries around the World across several continents. Diamonds reach the surface of the earth via volcanic pipes or via placer / alluvial deposits. Kimberlite is the name of the blue rock that occurs in ancient volcanic pipes and is the most common host of diamonds. Sometimes the Kimberlite host rock is washed away by streams and rivers and diamonds are deposited as sediment in the stream sands in 'placer deposits' which also called Alluvial deposits.

Areas containing Diamond Mines
Diamonds, and consequently mines, are found in areas where there have been volcanic activity or erosion and where natural elements such as streams, rivers and even glaciers might have taken them.

Diamond Mines - Strip Mining and Placer or Alluvial mining
Strip Mining is the process of mining thin seams near the surface by stripping in successive layers. Placer mining  (pronounced "plass-er") is the process of mining (by panning or dredging) alluvial (waterborne) or even glacial deposits of diamonds without tunnelling.

Definition of Diamond Mines
The purpose of the mines is the extraction of valuable diamonds from the earth. The mines are plant operations built to extract diamond crystal from either underground or from the surface. When diamonds are extracted underground, the mine needs a system of excavations in the rock to gain access to the kimberlite rock. There are a limited number of commercially viable diamond mines currently operating in the world which use tunnelling and excavation methods. However, diamonds are also mined using the Placer or Alluvial mining methods.

African Diamond Mines
The diamond mines in Africa are located in South Africa, Namibia, Botswana, the Democratic Republic of Congo, Angola, Tanzania and Sierra Leone. The civil unrest in West Africa has lead to the illegal trade of diamonds to finance wars - the infamous Blood Diamonds. The type of mining in Sierre Leone and Liberia  is using the Alluvial method by sifting through river-bank sand and gravel. The names of the African diamond mines are as follows:

  • Angola - The Catoca, Fucauma and Luarica diamond mines

Russian Diamond Mines
The names of the Russian mines are as follows:

  • Aikhal
  • Anabar Mirny Nurba Udachny Botuobinskaya Pipe Project Yubeleyniy Project

Indian Diamond Mines
Most all of the Diamond mines in India were depleted centuries ago. The majority of the diamond mines and deposits in India were alluvial as opposed to kimberlite. The most prolific area was in Golconda which yielded some of the worlds most famous diamonds including the Kohinoor Diamond, Hope Diamond, the Regent Diamond, the Sancy Diamond and the Florentine Diamond. There is only one active diamond mine left in India which is located at Panna in the central Indian state of Madhya Pradesh.

Diamond Mines in Canada
