Las Lagunas Gold Tailings Project - Mining

The tailings stockpiled at the dam are being processed using Xstrata’s Albion oxidation and carbon-in-leach (CIL) techniques. They are retreated through the Albion oxidation process followed by the standard CIL method to produce high grade gold and silver dore bars. The Albion oxidation processing plant can treat 800,000tpa of ore.
