The Nsuta Manganese Deposit — Ghana SpringerLink

高达10%返现 Abstract. This relatively simple deposit illustrates the way manganese oxide Minerals can accumulate in a laterite profile. The manganese originated as a metamorphosed manganiferous sediment; quite unworkable in itself, but which has been concentrated on an old erosion surface, and which also carries ferruginous and aluminous laterites.

Nsuta Mine (Insuta Mine; Nsuta-Gaywin Manganese concession

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.

Manganese Ore Exports from Ghana

Ghanaian Export of Manganese Ore. Ghana is a major producer of manganese carbonate ore, an essential element needed for processing stainless steel. Mining began in 1916, controlled by the American- owned African Manganese Company, and this continued until 1975, when production was taken over by the government owned National Manganese Corporation.

Nsuta (Ghana) is one of the most important Precambrian manganese deposits of the world. It is hosted in a package of metamorphosed volcanic and sedimentary rocks belonging to the 2.1 Ga old Birimian Supergroup. Metavolcanic greenstones, derived from a basaltic to andesitic protolith contain intercalations of various carbonate phyllites and silicate marbles.
