Orapa is of open pit construction and is the largest diamond mine in the world by area. The mine is located on two kimberlite pipes that converge near the surface, covering 1.18 square kilometres at ground level. Orapa operates seven days per week, and produces 20 million tons per year of ore and an additional 40 million tons per year of waste rock. In 2003, the Orapa mine produced 16.3 million carats (3260 kg) of diamond. The recoverable ore grade at the mine is about 0.87 carats (174 mg) per ton. The mine was expanded in 1999, doubling its previous capacity. The processing plant at Orapa processes the ore produced at Orapa as well as two of Debswana's three other mines, the Letlhakane and Damtshaa diamond mines.
Orapa and its sister mine Letlhakane employ over 3,100. Debswana also maintains a 100-bed hospital, pre-primary and primary schools for employees' children, and the Orapa game park. The mine maintains an ISO 14001 certificate for environmental compliance, and places some importance on water conservation and waste management.
