This ensures that the iron and manganese stays in a soluble form. If the water contains less than 1.0 mg/L iron and less than 0.3 mg/L manganese, using polyphosphates followed by chlorination can be an effective and inexpensive method for mitigating iron and manganese problems. No sludge is generated in this method.

Manganese and silicon are crucial constituents in steelmaking, as deoxidants, desulphurizers and alloying elements. Silicon is the primary deoxidizer. Manganese is a milder deoxidizer than silicon but enhances the effectiveness due to the formation of stable manganese silicates and aluminates. It also serves as desulphurizer.

Manganese Ore Process Plant. 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. Manganese tarnishes slowly in the air and oxidizes ("rusts") like iron in water containing dissolved oxygen.
