Geochemistry of the Nsuta Mn deposit in Ghana:
Oxygenation of the atmosphere and oceans has influenced the evolution of ocean chemistry and diversification of early life. A number of large manganese (Mn) deposits are distributed in the Paleoproterozoic sedimentary successions that were formed during the great oxidation event (GOE) around 2.4-2.2 Ga (Meynard, 2010). Due to the high redox potential of Mn,

The Major Epochs and Phases of Manganese
2017年1月1日 The major divisions of Geologic Time— Archean, Proterozoic, and Phanerozoic—each contain major manganese metallogenic episodes unlike iron, for which large deposits only occur close in time to the Archean/Proterozoic boundary. However, within each Era, commercial-scale manganese genesis was confined to relatively brief

Microbial metallogenesis of early carboniferous
2021年9月1日 1. Introduction. Manganese is an important element in industry and in life, and it has been considered as a good redox indicator, because manganese enrichment is always linked with an oxic environment (Canfield et al., 2005, Roy, 2006, Maynard, 2014, Johnson et al., 2016).The first metallogenic peak for sedimentary manganese deposits

Why Ghana's industrial minerals and lithium are forecast
1 The mine is ran by the privately owned Ghana Manganese Company, the country’s sole producer and exporter of this product. Other areas with manganese deposits include the north-west and south-west coast. Ghana also has deposits of around 900m tonnes of bauxite, according to GIADEC, located in the Awaso, Nyinahin and Kibi regions.

Compositional variations in manganese carbonate
2003年1月1日 The Nsuta manganese deposit is located in the early Proterozoic upper Birimian system of the West African craton. The manganiferous bed is concordant and contemporaneous, for over 5 km of outcrop, within a sequence of interbedded, dark grey to black highly pyritic argillaceous rocks which are, in turn, enclosed in greenstone.

2022年8月1日 South Africa’s manganese producers generally process a portion of manganese ore into ferromanganese prior to export to steel manufacturers, mainly in China. Gabon exported unprocessed ore until opening a $400-million smelter in 2015 (Mining Review Africa, 2015). Other countries like Ghana and Côte d’Ivoire export unprocessed ore.

The deposit consists of a manganese oxide zone, which is now mined out, and an underlying manganese carbonate zone which was discovered in 1968. Owned by the African Manganese Co. from 1923, then owned by Ghana National Manganese Corp. Produced 267,996 tons of ore (1984). Located about 20 km SE of Tarkwa.
