Mining in Gabon

Gabon was the richest of the former French Equatorial African colonies in known mineral deposits. In addition to oil, which accounted for 80% of the country's exports in 2004, Gabon is a world leader in manganese. Potash, uranium, niobium, iron ore, lead, zinc, diamonds, marble, and phosphate have also been discovered, and several deposits are being exploited commercially. Ownership of all

The most important manganese ores are the oxides pyrolusite, romanechite, manganite, and hausmannite and the carbonate ore rhodochrosite. Rhodonite and braunite, both silicate ores, are frequently found with the oxides. Only ores containing greater than 35 percent manganese are considered commercially exploitable.

Manganese Mining and Processing Everything you Need to Know

More than 25 million tons of manganese are mined every year. Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with landbased mining production. Once the ore is mined, its transferred to a processing plant for electrolytic processing or smelting.
