Manganese is the 12th most abundant element in the earth's crust. According to the data released by USGS (United States Geological Survey), global manganese reserves are about 570 million tonnes (metal content) with land-based manganese resources distributing irregularly in 2014, and world manganese mine production was estimated to be 17 million tonnes in 2013.
Dec 02, 2014· The Kalahari manganese fields, among one of the world's biggest and richest, has a relative newcomer; the new Tshipi Borwa mine owned by Tshipi Manganese Mining. With a 60-year mine life, and a 2 ...
manganese and nclanganiferous ores were mined. After World War I production dropped to almost nothing until World War 11, during which period more than 24,000 long tons were produced. A lull in manganese mining occurred after World War 11, having production rates of only a few hundred tons annually through 1952.
Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to
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.
Montezuma Mining Company Ltd: The Butcherbird Manganese project is located 120 km south of Newman. A scoping study was conducted into the development of a mine with capacity to produce up to 1 Mtpa with a mine life of at least 10 years. The study showed excellent potential for the commercial development of the Butcherbird manganese project.

Manganese, the fourth most widely used metal in the world, is present in the composition of these, and many other objects of your everyday life. We are a leading producer of manganese, an essential steelmaking input, and also of ferroalloys – combinati ons of iron and one or more chemical elements, such as manganese itself.
Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.
