Extraction of Manganese by Leaching

Extraction of manganese from the umber was about 87 percent. A gradual decline in the solids content of the underflow discharge did occur during the 15 days of operation. Allowing time for removal of stored residue, data from the last 6 days of this decline were subjected to the Grear regression analysis to determine the rate of solids content ...

The Kinetics of Iron and Manganese Removal

Aeration and filtration has been used for iron and manganese removal for a long time. During aeration, the water is exposed to oxygen. The oxygen is used to oxidize the iron, which is then filtered through some sort of filtration media (i.e. a multi-media filter). An even more effective aeration technique is the use of ozone.

TDS: Softeners remove manganese best if the total dissolved solids (TDS) of the water is low. When TDS is high, other minerals in the water compete with the manganese for space on the resin and can even displace manganese which has attached to the resin. Water with <500 ppm TDS works best for manganese removal by a water softener.
