Openpit mining is the most common method of recovering its diamonds, says international diamond company De Beers, which operates several opencast mines in Africa, namely South Africa and Botswana. De Beers Consolidated Mines (DBCM), formed in 1888, is South Africa’s largest rough diamond producer, with two openpit mining operations – Venetia, in Limpopo, where the company is constructing an underground mine, and Voorspoed, in the Free State. It also has surface diamond recovery operations at its Kimberley diamond mine, in the Northern Cape.
