Production at Aughinish Alumina commenced in September 1983 after a five-year construction period.

Aughinish Alumina Refinery is one of the most technologically-advanced and efficient alumina refineries in the world, one of Europe’s largest, and a major alumina asset of the Group.

Key infrastructure includes a deep water terminal on the Shannon estuary, a bauxite ore crushing and grinding plant, a single digestion processing unit, a hydrate processing plant, several gas-fired calcination units, and a gas-fired cogeneration plant.

In 2017, a second unloader was successfully installed and commissioned at Aughinish under a three-year project extensively upgrading its civil, mechanical, and power/control infrastructure.

In 2018, Aughinish brought online a new deep cone thickener in the mud circuit. This will help the settling the pond of plant to handle the different bauxites that are expected in the coming years.

Development plans

Major developments at Aughinish over the next three years will prepare the refinery for different bauxites whilst maintaining its reliability.
