Unfor­ tunately iron and silica percentages are increased at the same time, and sintering, apart from meeting sizing requirements, is only of real value with carbonate ores. METHODS OF TREATING

Specifics Water treatment manganese removal

Manganese is an element that is often found in the ground. Many manganese ores can be found, mainly oxides (pyrolusite, vernadite, etc.) and occasionally carbonates (rhodochrosite), silicates, sulphides, etc. In natural water, manganese will usually be present in the soluble ionised form, Mn 2+, and sometimes as MnOH + (very basic pH).
