The modern name "manganese" was derived from the 16 th century name for manganese dioxide, manganesum. The pigments from several colored manganese oxides, such as manganese dioxide, have been used by men since the Stone Age, as is the case in the Gargas cave paintings. These have been dated as 24,000 to 30,000 years old.

To address this, manganese (II) can be oxidized to insoluble manganic dioxide (MnO 2) and removed subsequently by a clarifiion or filtration process. Oxidation to this more insoluble form can be achieved by a combination of the right water quality conditions using aeration, chlorine, chlorine dioxide, permanganate or others.
