    Manganese - USGS

    Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.

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

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

    Elemental manganese readily combines with oxygen, carbon, and silicon to form a long list of manganese minerals. Manganese ores generally contain 25 to 45 percent manganese, mostly in oxide (or hydroxide) and carbonate minerals. Manganese ores are widespread, but most of the world’s supply is from a small number of manganese mining districts.
