Anglo American owns 85% of De Beers, the world’s leading diamond company. The remaining 15% of De Beers is owned by the Government of the Republic of Botswana (GRB).
The 74% interest in De Beers Consolidated Mines (DBCM) is held indirectly through De Beers Société Anonyme (De Beers). The 74% interest represents De Beers’ legal ownership share in DBCM. For accounting purposes De Beers consolidates 100% of DBCM as it is deemed to control the BEE entity which holds the remaining 26%. The Group’s effective interest in DBCM is 85%.
Summary:
The Lower Cretaceous Voorspoed kimberlite pipe is one of the six pipes which comprise the Kroonstadt Kimberlite Cluster located in the central region of the Kaapvaal Craton (South Africa). The pipe was initially described as a typical South African tuffisitic kimberlite (Skinner, Marsh, 2004) and later on as a pipe with a 2 km deep crater filled by pyroclastic sedimentation and resedimentation of kimberlite and country rock debris (Howarth, Skinner, 2012) due to the presence of bedded volcaniclastics at a depth of 2 km from the original land surface.
Summary:
De Beers Voorspoed mine is an open-pit kimberlite mine that is situated 30 kilometres northeast of Kroonstad in the Free State, South Africa.

Summary:
The plant includes the installation of high pressure rolls crushers to replace the relatively dated rod milling process used before, and two new secondary crushers, replacing the older technology cone crushers. The efficiency improvements have been achieved with the addition of a coarse Dense Medium Separation (DMS) Plant and by converting the existing DMS plant to a fines DMS plant, thus allowing for a more efficient DMS process. This will feed correctly prepared diamond bearing kimberlite to a new final recovery plant that includes the latest X-Ray diamond recovery technology. Much of the technology installed at Finsch was developed by DebTech, the De Beers Group’s technology research and manufacturing division based in the south of Johannesburg.
