South African manganese deposits are currently confined to the Early Proterozoic Transvaal Supergroup, Northern Cape Province. They can be grouped into two major egories: 1. Syngenetic carbonaterich manganese deposits interbedded with the banded iron formations (BIF) of the Hotazel Formation, colloquially called the Kalahari Manganese Field. 2.

of hydrothermal exhalative manganese deposits in ophiolitic regions and recent submarine spreading centers [,, ]. e SiAl discrimination diagram, proposed by Peters [ ], is used to distinguish hydrothermal from hydrogenous Mnoxide deposits. Buyukmahal ore samples are almost within the eld of hydrothermal eld, with only one sample
Manganese ore deposits occur in a great diversity of host rocks such as carbonate, siliciclastic, volcanic and metamorphic rocks and range in ages throughout geologic history. Marine manganese oxide deposits are classified based on their mineralogy, composition and tectonic settings as hydrogenous, diagenetic and hydrothermal

· Two belts of manganese ore deposits have been distinguished in the PMF, namely the Western Belt of ferruginous manganese ores and the Eastern Belt of siliceous manganese ores. Prevailing models of ore formation in these two belts invoke karstifiion of manganeserich dolomites and residual accumulation of manganese wad which later underwent diagenetic and lowgrade metamorphic processes.

The Marau Manganese Deposit is near Ubaitaba, Brazil. The Marau Manganese Deposit was closed at the time of data entry with no known plans to reopen. The ore mined is composed of hollandite, spessartite and lithiophorite with waste material consisting primarily of graphite. The ore body has a lenticular or lens shaped form 5,000 meters (16,404 ...
The major deposits in the Northern Cape are the Hotazel, Wessel and Mamatwan ores. The Mamatwan deposit has the largest ore reserves. Manganese ore minerals occur in several forms as oxides, silies and carbonates. Typical ore minerals are braunite, braunite II, bixbyite, hausmannite and manganite(1,2,3). Uses of Manganese and ...
