Natural richesse in Gabon extends well beyond the country's sizeable oil and gas reserves and fertile soil. Based on forecasts for production and processing of manganese, the mining sector's primary output, along with gold, iron ore and poly-metallic deposits, the sector's GDP contribution could grow from its current 6% to as much as 25% within the next 15-20 years, according to Fabrice ...
The ore is extracted from an open-cast mine on the Bangombé plateau. This world-class deposit is one of the largest on the planet, with an ore content of 46% manganese. After the extraction, the ore is processed in a washery to be crushed, ground, washed and sorted, before being shipped to the Moanda Industrial Complex (CIM) for enrichment.

It is a world-class chemical sedimentary deposit with an annual production of ~1.8 Mt, equivalent to 10% of world supply. Most of the ore is exported, with some shipped to Bell Bay in Tasmania for the production of manganese alloys (~200 000 t/year). World resources of manganese ore are large, but irregularly distributed, and of low-grade.

The manganese mineralization in ore deposits ranges in thickness from a fraction of an inch to about 10 feet. The deposits, which contain a large amount of low-phosphate manganese in the aggregate, are usually small and discontinuous. Exploration in the district is incomplete. A few mines and prospects are well known and minor production by ...
Therefore, imported manganese ores are used at domestic ferroalloy plants to obtain high-quality manganese ferroalloys with reduced content of phosphorus. The annual Ukrainian import of manganese ore is about 1.8 million tons. The largest exporters are: Ghana (39%), Gabon (26.5%), Australia (10.5%) and Republic of South Africa (10.45%) [4].
The Moanda Manganese Mine is near Moanda, Gabon. The site was first discovered in 1934 by Choubert, B. & Berge, J. The ore mined is composed of manganite, pyrolusite and lithiophorite with waste material consisting primarily of illite, kaolinite and limonite. The ore body takes a blanket shape of unknown dimensions.
The government is seeking to diversify the mining companies operating in Gabon. The Directorate General of the Economy and Tax Policy (DGEPF) revealed that Gabon had produced 1.109 million tons of manganese in the first quarter of 2018, compared to 827,551 tons during the same period in 2017, an increase of 27.2%.
Gabon is the world's third-largest producer of highgrade manganese, with output of 3.5m tonnes in 2014 and reserves of at least 250m tonnes as of end-2014. It also has more than 1bn tonnes of iron ore, more than 40 tonnes of proven gold reserves, and 22,400 tonnes of lead and zinc, according to the Ministry of Industry and Mines.

The manganese deposits in Moanda, Gabon are some of the richest in the world and contribute to Gabon being a world leader in manganese mining and production. Manganese mining is one of the most important income generators in the country. It is estimated that the manganese reserves in Gabon will last another 100 years. History of Gabon Mining
Gabon is currently the world's third producer of manganese behind South Africa and Australia. 95% of the Gabonese production is for the steel industry. Deposits are mostly located in the south-east of the country in the Francevillian basin of Proterozoic age.
a) Ore Denosits 11. The Comilog ore deposits are near Moanda, about 50 km. northwest of Franceville, Gabon Republic (see lJap 3). The ore consists of manganese-bearing boulders, fragments and grains in a sandy clay matrix covering four plateaus (Bangombe, Okouma, Bafoula and iiassengo). Some ore also is indi-cated on the Yeye plateau.
Mineral deposit - Mineral deposit - Iron deposits: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world's great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so ...
