Our Operations


After completing its journey through the concentrator, the concentrate is placed into two tonne bags, stamped with “Product of Mongolia,” and loaded onto trucks. These trucks then depart in convoys to the Gashuun Sukhait border crossing, 80 kilometres to the south of Oyu Tolgoi. After arrival at the border warehouse, the concentrate is ready for collection by customers. After payments are collected, a royalty is paid to the Government of Mongolia. This royalty is calculated according to the amount of metals contained in the concentrate.

Each quarter, the amount of concentrate produced and exported is published online. You can find the latest releases of this information in our news page.

After being sold, Oyu Tolgoi’s concentrate goes to smelters which further refines it into more pure metals. After this processing, the copper, gold, and silver is used to make many of the products that the world relies on today. You can find out how Oyu Tolgoi’s metals are helping the world develop from ‘copper and the world’ page.
