Iron and Manganese Ore Deposits Mineralogy

The majority of ore deposits of both iron and manganese are of sedimentary origin. At present high-grade iron ore deposits formed by hydrothermal and supergene enrichment of Proterozoic banded iron formations constitute the most important source for iron ores with only some magmatic and skarn-type iron ore deposits being mined.
