MANGANESE
The ores often are associated with other metals, particularly with iron oxides and silver ores. Like residual limonite, manganese ore is a secondary product resulting from the removal of more soluble substances during the weathering of slightly manganiferous rock. Manganese occurs in a wide variety of oxide, silicate and carbonate minerals.
