Iron and Manganese Removal

Most iron and manganese removal treatment processes incorporate oxida-tion to convert the dissolved forms of the metals to a solid, followed by a filtration process. When concentrations in the source water are above 8 to 10 mg/L combined iron and manganese, a clarification step is typically required prior to filtration.

Extraction and separation of manganese and iron from ...

In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+, Mn 4+ must be converted into Mn 2+, therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).

A deliberate addition of a separate manganese-rich material has previously been documented in the bloomery smelting of Harthorpe Mill in County Durham (Tylecote, 1962: 288). Fifteenth century smelters were using nodular iron ore with a manganese content of less than 1wt%, yet contemporary slag remains contained up to 7wt% manganese oxide.
