Compagnie des Bauxites de Guinée

[3] Bauxites du Midi partnered with the Canadian company Aluminum Laboratories, which proffered the necessary funds and materials for the deposit facilities in Guinea, and additionally worked to provide the specialists required to construct an enrichment plant on Île de Kassa [fr].

[3] In 1948 and 1950 the Guinean bauxite from the Îles de Los was shipped in small quantities to the Aluminum plants of Alcan in Saguenay-Lac-Saint-Jean in Québec, but in November 1966, that deposit was depleted, as was expected, despite nationalization.

Under the leadership of Pierre Jochyms, the planning of the utilization of significant deposits of bauxite (in Kassa, Boké and Fria), Iron ore (on the Kaloum peninsula and the Nimba-Simandou island chain) gold and diamonds was begun.

The exceptional hydroelectric potential of the Konkouré watershed had already been identified, and two large dams were being researched (Grandes Chutes and Souapiti)[4] CBG began its first excavations in January, 1955, then suspended them for one year.

[7] In 1967, the participation of Harvey Aluminum of Delaware was divided amongst several players in the mining sector: Alcan took 33%, Alcoa 27%, Martin Marietta 14%, Péchiney 10%, and Edison-Montecani 6%.

[5] Simultaneously, the site of Débélé in the region of the Kindia mine was made operational before 1974[5] after an agreement in November 1969, by a joint project of the Soviet Union and the Guinean government, which established the price of ore and announced that the Guinean state is fully the proprietor of said capital, the Soviet Union having assured the purchase of 90% of the ore. Exports passed from 2 million tons in 1974, to more than 3 million in 1988.

[5] In November, 2012, CBG signed a historic agreement with the Mubadala Investment Company to supply the United Arab Emirates with bauxite [9] In December, 2013, Namory Conde, then regional director of BHP Billiton, was named director-general of CBG [10] The ore, reputed to be of excellent quality due to its 60% alumina content,[11] is transported by rail to the port of Kamsar.
