ULAN BATOR, Dec. 27 (Xinhua) -- Anglo-Australian mining group Rio Tinto commissioned its largest copper concentrator to the gold-copper deposit Oyu Tolgoi in the southern Gobi region in Mongolia on Thursday.
Mongolian Mining Minister Davaajav Gankhuyag attended the commission ceremony, according to a press release of Oyu Tolgoi.
"From the signing of the investment agreement to activating the concentrator, Oyu Tolgoi's progress has been remarkable," said Rio Tinto Mongolia manager Cameron McRae.
"We are doing more than just constructing the most technologically advanced mine in Mongolia's history. We are also helping to usher in a new wave of economic development."
The Oyu Tolgoi mine has an estimated deposit of more than 31 million tons of copper, 1,328 tons of gold and about 7,000 tons of silver.
The project was on the verge of becoming a world-class mine.
