Megadoor

The world's largest undeveloped copper deposit, which also turns out to include significant deposits of gold and silver, is located in the Gobi of Mongolia at a site called Oyu Tolgoi, which means "Turquoise Hill". The Oyu Tolgoi site is the signature feature of Ivanhoe Mine's flagship project.

The concentrator's quickly evolving shape is a barometer of the pace of the full-scale construction now underway on what will be one of the world's largest copper, gold and silver mining complexes. The concentrator initially will process 100,000t of ore each day mined from the open pit, increasing to up to 160,000t a day when ore from the underground mine is added in 2015. During the first 10 years of production, the complex will produce a projected average of 1.2 billion pounds of copper, 650,000 ounces of gold and three million ounces of silver every year.

Challenges / critical issues

High wind load: Wind speed in the Gobi desert can reach up to 200 km/h. Doors need to withstand the wind loads of hurricanes.

Cold weather: Winter temperature in the Gobi desert can reach as low as -40° C. All building facilities and equipment must perform at extremely low temperatures.

Excessively dusty condition: The dust and sand in Gobi desert makes the building difficult to keep clean. The workshop needs to stay clean for equipment / truck repairs and maintenance.

No immediate service: Immediate service is difficult to achieve in the deep desert. All facilities need to be reliable and stable. Highly reliable equipment with low service and maintenance needs help to keep downtime to a minimum.
