Alumina Company of Guinea (ACG-Fria) is a bauxite mining and alumina refining operation located in Fria, western Guinea, that holds the distinction of being Africa's first alumina refinery. Originally established under French control in the 1970s and now majority-owned by RUSAL since 2006, the facility processes 2.1-2.8 million tonnes of bauxite annually to produce 600,000-650,000 tonnes of alumina—the intermediate product used in aluminum production.
ACG-Fria serves as the primary economic driver and employer for the town of Fria, which was essentially built around the refinery, and has historically been Guinea's only alumina processing facility, making it strategically significant in a country that ranks among the world's largest bauxite producers. The company represents Guinea's efforts to add value to its mineral resources locally rather than simply exporting raw bauxite, a strategy that is being expanded with new refinery projects planned by other international partners.
Alumina Company of Guinea (ACG-Fria) Overview
ACG-Fria is a bauxite mining and alumina refining operation located in Fria, a town in the Boké Region of western Guinea. Fria was originally developed around this plant, which was Africa’s very first alumina refinery.
Ownership history
Initially established under French control (Pechiney/Ugine group) and later as a joint venture (Frialco) between the government (to 1998) and international partners.
Reynolds Metals managed operations under a contract, with the government retaining a stake. In the early 2000s, Reynolds was acquired and partly replaced by RUSAL. In 2006, RUSAL consolidated ownership by purchasing most of the government’s interests.
Capacity and production
The refinery processes bauxite into alumina (the intermediate for aluminum production), with historical output estimates between 600,000 and 650,000 tonnes of alumina annually, and 2.1 to 2.8 million tonnes of bauxite per year.
Socioeconomic footprint
ACG-Fria is the primary employer and economic driver for Fria, the town itself owes much of its development to its presence. The refinery also originally included infrastructure for electricity, water, housing, medical services, schools, and transportation for employees and locals.
Role in national mining landscape
ACG-Fria is historically Guinea’s only alumina refinery until recent years, giving it strategic significance.
Guinea remains one of the world’s largest bauxite producers and has been pushing for increased local processing (i.e., refining into alumina) to capture more value locally.
Recent Developments in Guinea’s Alumina Sector
Guinea has signed a non-binding “term sheet” with Emirates Global Aluminium’s (EGA) subsidiary, Guinea Alumina Corporation (GAC), aiming to build a second alumina refinery with a capacity of 2 million tonnes per year, scheduled for completion by September 2026; initial production would be 1.2 million tonnes annually. The estimated investment for the project is around $4 billion, in partnership with Chinalco (China).
The Guinean government would hold a stake (15% total—10% in the mining operations and 7.5% in the refinery) and two board seats in the new venture.

Final Thoughts
ACG-Fria has long been the bedrock of Guinea’s alumina refining industry. As the nation aims to enhance domestic value addition, the upcoming refinery project by GAC promises to significantly expand local processing capacity, economic development, and industry diversification in Guinea.
