Manganese (Mn) - Chemical properties, Health and ...

Manganese is a pinkinsh-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids. Applications. Manganese is essential to iron and steel production.

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.

Manganese removal physical-chemical way - Lenntech

Manganese does not present a danger to human health, nor for the environment but it is unpleasant. In fact, the water gets a black color and a metallic taste. Similar to iron, the manganese removal by physical-chemical way, can be carried out by the oxidation of Mn 2+ in Mn 4+, which precipitates then in manganese dioxide (MnO 2).

Treating Manganese in Well Water – Pure Water Products, LLC

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.
