Here are the five largest iron ore mines by production in South Africa, according to GlobalData's mining database.
The Kolomela mine is located 22km from Postmasburg in the Northern Cape province of South Africa. The mine produces direct shipping iron ore.
Geochemical and field observations indicate that the Blue Dust in these deposits is regarded to be of supergene-modified hydrothermal origin. In the first stage, the early hydrothermal process affects the primary unaltered Banded Iron Formation by simultaneously oxidising magnetite to martite and replacing quartz with hydrous iron …
The iron ore deposits forms part of Pre-Cambrian iron ore formations occurring as narrow, highly deformed and metamorphosed belts with in Archaean granulites and gneisses older then 3,000 Ma.
A pocket of blue dust in BIF and ore bodies indicates in-situ leaching of flux-materials and consequential concentration of iron materials. Between Thakurani and Bolani hills sits Barbil on such a deposit, huge in nature but only at depth and partly mined.
