Lihir Gold Mine

The gold deposit at Lihir is within the Luise Caldera, an extinct volcanic crater that is geothermally active, and is one of the largest known gold deposits in the world. Most of the ore is refractory and is treated using pressure oxidation before the gold is recovered by a conventional leach process. Lihir produces gold doré.
