The project is located in Boffa Province, Guinea. The investor is Chinalco (Aluminum Corporation of China) Guinea Co., Ltd. HHI undertook the engineering, supply and installation services of the bauxite handling system from the mine to the terminal. The belt conveyor system of this project has the highest belt speed, the largest handling capacity, the most complicated operating conditions and tension system, and is the longest at open-pit mines in both China and Guinea. In addition, the C07 belt conveyor (Length = 12.3Km) of this system is the longest single-belt conveyor in Africa. Unit energy consumption of this system is the lowest in the world. Compared with material handling systems of similar scale,  HHI offered the highest efficiency and the shortest time of construction on this system.
