The AQW Conference is a specialized workshop focused on quality in bauxite and alumina refining processes. The inaugural conference was held in 1988 in Glendinning, the site of the QAL alumina plant. It is held every three years, and this year marks the 12th edition.
The Alumina Quality Workshop was officially established in 1990 as a registered non-profit organization. The AQW (Inc.) Executive Committee is composed of representatives from Australia’s major alumina producers, and the chairperson (and moderator) of each meeting rotates among them. The committee has since expanded to include Hydro, EGA, and the International Aluminium Institute (IAI), which represents the global bauxite-to-aluminium industry.
In addition to sharing the latest industry trends and technological advancements, the organizing committee has arranged a visit to the EGA alumina plant. At EGA, PL&A’s A/C meters and caustic-soda meters (installed in immersion mode within the digestion tanks) are in use, along with 14 sludge-interface instruments (EGA operates two production lines, each capable of processing 2.5 million tons of alumina annually; the settling process involves a total of three separation stages and four washing stages, with two sludge-interface instruments installed above each tank. In daily operations, only five tanks are in use, while two remain as backups).
