Alumina

World leadership in production and sustainability.

• World’s first and only low-carbon alumina brand, EcoSource^®.
• Installed capacity: 17 million metric tons/year.
• Six refineries in Australia, Brazil and Spain.
• Our three-refinery operation in Western Australia is the world's biggest single source of alumina, able to supply eight percent of the global market.

Alumina is a white, crystalline form of aluminum oxide with a sand-like consistency. We are the world’s largest third-party producer.

Most of the alumina we produce is smelter-grade, used to make aluminum metal. We also produce what’s known as non-metallurgical alumina, sold for a variety of industrial applications such as water purification and creation of refractory.
