Compagnie des Bauxites de Guinée

Compagnie des bauxites de Guinée (CBG) is a Guinean mining company. Since 1963 it has extracted bauxite from the notable mine in Sangarédi, in Boké Region in Guinea.

Guinea is the world's 5th largest producer of Bauxite, yet the country holds the world's largest reserves of the valuable ore used to produce aluminum. Estimates of the country's reserves rise as high as 25 Billion tons, or the majority of the world's bauxite .

History

The first plant of Bauxites du Midi in Guinea.

CBG in Kamsar.

Guinea possesses a third of the best bauxite reserves in the world, or about 20 billion tons, with a high content (45-62 %) of alumina and a low silica content

(0,8-2 %). Despite being ranked second after Australia in terms of production, it was, in 1993, the largest exporter in the world, having benefited from the relocation in the world aluminum industry in the 1970s; After global production tripled between 1950 and 1960, it doubled again in the 70s, which saw a strong consolidation around six companies: (Alcan, Alcoa, Reynolds, Kaiser, Pechiney Ugine Kuhlman and Alusuisse) as well as a strong vertical integration, as a result of which, in 1979 the members of the International Association of Bauxite Producing Countries supplied 75% of the world's bauxite, while only providing 4.5% of the world's Aluminum.

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

July 24, 1948, 20 mining exploration permits were awarded to the company. They discovered that the bauxite deposits of guinea consisted of surface deposits which are entirely exploitable using mining pits and heavy vehicles. Bauxites du Midi partnered with the Canadian company Aluminum Laboratories Limited, which proffered the necessary funds and materials for the deposit facilites in Guinea, and additionally worked to provide the specialists required to construct an enrichment plant on Kassa . In 1948 and 1950 the Guinean bauxite from the Îles de Loos 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.
