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.

For example, the high sulfur content in iron ores will reduce the metal tensile strength, making steel brittle at a high temperature. In addition, too much phosphorus in iron ores also makes steel brittle when cooling. Therefore, the study of ore can guide the selection of the correct beneficiation process of discarding gangue minerals and ...
