Guinea Alumina Corporation is our wholly-owned bauxite mining subsidiary in the Republic Guinea, West Africa. Bauxite is the ore from which aluminium is derived. Exports of bauxite ore began in 2019.
GAC operates a 690-square kilometre mining concession, located in the northwest of Guinea. Once mined, bauxite is transported to GAC’s port at Kamsar by train using shared rail infrastructure.
Bauxite from GAC is predominantly supplied by EGA to third-party customers, with some shipped to our Al Taweelah alumina refinery in Abu Dhabi.
A second phase of the GAC project envisages construction of an alumina refinery in Guinea, delivering further value for the nation.
GAC’s bauxite has one of the highest ratios of alumina to silica, as well as relatively low boehmite. These properties make it suitable for processing in a wide range of refinery operating conditions, from low to high temperatures as well as double-digestion refineries at comparably low operating costs.
GAC has some of the largest equipment ever installed on an African mining project. The stacker/reclaimer at Kamsar is is 125 metres long - longer than a soccer field - 25 metres tall, and weighs 1,300 tonnes.
GAC’s mine and port are some 90 kilometres apart. Trains transport ore to the coast. Each train consists of three locomotives and 130 wagons. Each wagon can hold 85 tonnes of ore.
Bauxite is loaded onto barges using a system of conveyors. EGA operates a transhipment location 37 kilometres away, in deeper water. This enables EGA to use vessels up to Capesize for ocean shipping.
Capesize vessels are around 300 metres long, 50 metres wide, and can carry some 180,000 tonnes of bauxite.
Some 2,600 people work at GAC. Some 93 per cent of GAC’s total workforce is Guinean.
GAC’s direct, indirect and induced economic impact in Guinea is estimated at $700 million per year, a 5.5 per cent boost to Guinea’s GDP.
From health awareness programmes to vocational training and environmental projects, GAC has invested more than $54 million in community initiatives and helped more than 190,000 people since EGA began its involvement.
Guinea is the world's largest bauxite resource holder, with more than a quarter of the known global endowment of this important mineral for modern life.
Guinea Alumina Corporation was built as part of our strategic expansion upstream in the aluminium value chain, creating new revenue streams for EGA and securing the competitive supply of raw materials we need.
