Manganese - Wikipedia

Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard brittle silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber additive, in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide.

PROPERTIES OF MANGANESE ORES AND THEIR CHANGE IN

properties of a manganese ore have a large influence on the technology and efficiency of the production of manganese alloys. The melting and reduction behaviour of ores are defined by their chemistry, mineralogy and physical properties, which change as the ore is heated in a reducing atmosphere in a ferroalloy furnace.

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.
