Overview

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Jwaneng diamond mine is the richest diamond mine in the world and is located in south-central Botswana about 120 kilometers (75 miles) west of the city of Gaborone, in the Naledi river valley of the Kalahari. Jwaneng, meaning a place of small stones, is owned by Debswana, a partnership between the De Beers company and the government of Botswana. It is the second newest of four mines operated by the company, having begun operations in 1982. Jwaneng is an open pit mine. The mine produces 9.3 million tons per year of ore and an additional 37 million tons per year of waste rock. The mine is located on three kimberlite pipes that converge near the surface, covering 520,000 square metres at ground level. In 2003, the mine produced 14.3 million carats (2860 kg) of diamond. The recoverable ore grade at the mine is about 1.25 carats per ton (250 mg/t). As of 2005, known reserves will allow production at current levels to continue for 27 years. The high rate of diamond extraction, combined with high quality diamonds fetching excellent per weight prices, make the Jwaneng diamond mine the richest diamond mine in the world by value of recovered diamonds.
