Higher-quality fines may be agglomerated, nodulised, sintered or pelletised. Lower-quality ores, fines and complex fine-grained ores may be flotated. In cases where manganese is associated with other metals, hydrometallurgical processes such as solvent extraction are used, sometimes after roasting or sintering to improve solubility, according ...

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.
