We are the world's leading producer of alumina. With installed refinery capacity of 17 million metric tons per year, we currently operate six refineries in Australia, Brazil and Spain, and have a 25 percent share in the refinery that is part of our Ma’aden joint venture in Saudi Arabia. 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.
In addition to supplying alumina to our own smelters, we sell more than half of our production externally. We provide smelter grade alumina to aluminum manufacturers worldwide, with operations strategically located for access to growing markets in Asia and the Middle East. We also produce non-metallurgical grade alumina for sale to industrial chemical operations in North America, Latin America, Europe and Asia.
World leader in refining technology
For nearly 50 years, our Australia-based Center of Excellence has been developing innovative equipment and processes for cleaner, more efficient alumina production. Technology developed by this group of scientific, engineering, chemistry and support staff has steadily increased our system-wide capacity by the equivalent of a new refinery over the past decade without greenfield development. In addition, Alcoa refineries have led the way in ISO9001 and ISO14001 certifications for quality and environmental performance.
