Compagnie des Bauxites de Guinée

Early on, the country attracted prospectors. Bauxites du Midi, founded in 1912 in Paris, began mining operations on Île Tamara [fr] in 1937, preceded by a prospecting voyage in 1936-1937^[3]

On July 24, 1948, 20 mining exploration permits were awarded to the company.^[3] They discovered that the bauxite deposits of guinea consisted of surface deposits which are entirely exploitable using mining pits and heavy vehicles.^[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. Pechiney Ugine began its major project in 1957, on the site of Fria.^[5] Studies were done on the hydroelectric project in Konkouré, to the east of Fria, but following a referendum on September 28, 1958, they were kept secret by the colonial authorities.^[5]

In November, 1961, the government took possession of the sites of Kassa and Boké due to the failure of Bauxites du Midi (a wholly owned subsidiary of Alcan) to respect its agreement to refine its bauxite into aluminum locally after 1964.^[5] In 1962, Guinea joined the World Bank^[5] and CBG resumed its excavations on October 1, 1963, under the banner of the Compagnie des bauxites de Guinée, of which 49% ownership was held by the state of Guinea, and 51% by Harvey Aluminium of Delaware.^[6]

Bauxite exports began in 1973.^[7] The first ship loaded with Guinean bauxite left the port of Kamsar on August 2, 1973, with 19,000 tons of ore on board.^[8] In the 1970s, Africa's portion of global bauxite production tripled.

In 1965, the Boké Improvement Office (OFAB) was created to construct and manage CBG's infrastructures.^[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%.^[7] At the end of the 70's, Fria exported more than 600,000 tons of alumina annually,^[5] of which a part went to the Pechiney's facilities at Edea in Cameroon,^[5] with two large foreign investors: Noranda (Canada) 38.5% and Pechiney Ugine Kuhlman (France) 36.5%.^[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]

At the Boké site, the quantity of exports shifted from around 5 million tons in 1975 to 11 million in 1990.^[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. The ground of Guinea contains 300 million tons of bauxite, which is enough to ensure production for at least 25 years.

If CBG is vital for the regional and national economy of the nation, it is also accused of being responsible for numerous instances of pollution - toxic dusts and the dumping of fuel oils into the sea - and this, despite an investment of 17 million to reduce dust emissions by 80% in 2005.^[12]

CBG exploits the mines of Sangarédi, of Bidikoum, of Silidara, and those of N’Dangara.^[8] The bauxite is intended for exportation, principally to North America, Europe and China.

In 2014, CBG undertook a project of expansion. This project would increase the capacity of the company's mining-production, of their rail transport, of their refinery, of their ports, of their electric generating stations and would generate new jobs and increase state-revenue ^[13]
