The Biniomi Manganese Mine is an integral component of the massive mining complex surrounding Moanda in the Haut-Ogooué province, which has positioned Gabon as the world's second-largest producer of high-grade manganese. The ore is extracted using open-cast mining techniques, employing advanced methods to ensure the high metallurgical quality required by international markets. Manganese is an essential element in global steel production, vital for enhancing the hardness and durability of alloys. Operations are primarily managed by the Compagnie Minière de l'Ogooué (COMILOG), a joint venture between the Gabonese government and the Eramet Group. The logistical chain involves transporting the ore via the Trans-Gabon Railway to the deep-water port of Owendo for global export. Biniomi significantly contributes to the diversification of Gabon's export economy and provides thousands of jobs in the region. The mine operates under rigorous certification processes to ensure sustainable mining practices and adherence to international social standards.
