The Smelting of Manganese Carbonate Ore

manganese carbonate ore was the principal mined product, not derived as a by-product. The purpose of the Mexican development was also different in that it was necessary to upgrade by calcination the run-of-mine ore, which analysed only 27% Mn, into a product containing almost 40% Mn [5]

Of the five erosional relics that the KMF comprises within the Hotazel Formation, the Kalahari Manganese Deposit (KMD) is the largest. The Mn ores within the KMD are hosted in three beds that alternate with banded iron-formation (BIF) and hematite lutite. The low-grade ore (44 wt% Mn), is a carbonate-free, Mn oxide-rich ore.

Geology and ore genesis of the manganese ore

The Postmasburg Mn/Fe-ores occur exclusively in dolomitic Precambrian sinkhole structures with siliceous breccias and shales as hostrocks. The main manganese minerals are braunite and bixbyite, apart from secondary alteration products of the psilomelane-manganomelane family. Various generations of ore minerals could be identified. The ore mineralization is subdivided into three different
