The oxidation process converts the minerals into their ferric (insoluble) form, making them easier to remove. Water then flows through a media bed, such as birm or manganese greensand, which further oxidizes and traps the insoluble particles, so that the water leaving the system is virtually iron and manganese-free.

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.

Manganese (Mn) is the twelfth most abundant element in the Earth's crust. Amongst some 300 minerals containing manganese, only about a dozen are of economic significance. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic.

Park et al. [34] used chlorine dioxide (ClO2) oxidant for selective leaching of nickel and cobalt from the precipitated manganese hydroxide. The process is selective, because manganese is dissolved and precipitated as MnO2 under the strong oxidizing conditions while nickel and cobalt tend to be preferentially leached into the solution.
