Production of mainly gem-quality diamonds has remained approximately 2 million carats (400 kg) per year since inception of the mine, mainly through improvements in technology. [citation needed] Oranjemund was proclaimed a town in 2011. [4] Until 2017 the town was run by Namdeb (formerly Consolidated Diamond Mines), now a subsidiary of De Beers ...
Small rough diamonds from Russia. Crystals are about 0.7 to 0.9 mm in size. There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. [1]
De Beers discovered the kimberlite A/K6, but their early evaluation showed low economic importance, the mine having only a 3.4-hectare surface area. The ownership was transferred three times. In 2009, De Beers sold their 70% shareholding in the mine to Canadian company Lucara Diamond for $49 million. Later, Lucara acquired full ownership of the ...
It is characterised by extremely low grade ore (less than 400 milligrams (2 carats)/hundred tons) and is known for producing huge diamonds, having the highest percentage of large diamonds (greater than 2 grams (10 carats)), giving it the highest dollar value per carat of any diamond mine.
The mine had production of 1,800,000 carats (360 kg) in 2000 and 2,600,000 carats (520 kg) in 2001. The mine's production is 35% gem quality, compared to a global average of 20%; the diamonds produced at Catoca have an average value of US$75–$100 per carat ($375–500/g). Estimated reserves are 60 million carats (12 tonnes).
The Jwaneng Diamond Mine is situated within the Orapa Kimberlite Field. [14] In the mine lies the "Jwaneng pipe," [15] a volcanic crater formed during the Permian period. [16] The mine consists of three kimberlite pipes. [17] Diamond-bearing ores are extracted from the vast pit and transported to processing facilities and manufacturing ...
An early map drawn by George Paton on the eve of the discovery of diamonds mentions 'Teuzpan' which, when pronounced in the German way, sounds the way local Dutch/Afrikaans-speaking farmers would have pronounced (Du) Toit's Pan. [2] The name refers also to one of the major mines in Kimberley, the Dutoitspan mine.
