Bauxite Ore Processing Plants: A Comprehensive List
Bauxite ore is the primary source of aluminum, and its processing involves several stages to extract alumina (Al₂O₃), which is then refined into aluminum metal. Below is a detailed list of major bauxite ore processing plants worldwide, along with their key features and locations.
1. Alunorte (Brazil)
Located in Pará, Brazil, Alunorte is the world’s largest alumina refinery, operated by Hydro. With an annual production capacity of over 6 million metric tons, it processes bauxite from the nearby Paragominas mine. The plant uses the Bayer process to extract alumina efficiently while adhering to strict environmental standards.
2. Queensland Alumina Limited (Australia)
Situated in Gladstone, Queensland, this refinery is a joint venture between Rio Tinto and Rusal. It produces approximately 4 million tons of alumina annually. The facility sources bauxite from Weipa and processes it using advanced refining techniques to minimize energy consumption and emissions.
3. Jamalco (Jamaica)
Owned by Clarendon Alumina Production and Noble Group, Jamalco operates a refinery in Clarendon Parish with a capacity of 1.4 million tons per year. The plant plays a crucial role in Jamaica’s economy, processing locally mined bauxite into high-quality alumina for export markets.
4. Worsley Alumina (Australia)
Located in Western Australia, Worsley Alumina is owned by South32 and produces around 4.6 million tons of alumina annually. The refinery sources bauxite from the nearby Boddington mine and employs innovative technologies to enhance efficiency and sustainability in processing.
5. Alumina Partners of Jamaica (ALPART)
ALPART’s refinery in Nain, Jamaica, has a production capacity of 1.65 million tons per year. After a temporary closure, it resumed operations under new ownership, focusing on modernized refining methods to improve output and reduce environmental impact.
6. Guinea Alumina Corporation (GAC) – Guinea
GAC operates one of Africa’s largest bauxite mining and refining projects in Boké, Guinea. The facility processes high-quality bauxite into alumina for global markets, supporting Guinea’s position as a leading bauxite exporter.
7. Rusal Aughinish (Ireland)
Europe’s largest alumina refinery
