Iron And Manganese Ores

Manganese Wikipedia

The manganese content of some iron ores used in Greece led to speculations that steel produced from that ore contains additional manganese, making the Spartan steel exceptionally hard. Around the beginning of the 19th century, manganese was used in steelmaking and several patents were granted. In 1816, it was documented that iron alloyed with

Although manganese ores are not as cheap as iron ores, they are still low cost. Manganese ores are available in several oxidation states, and often the manganese combines with other elements to form a number of different minerals. As Si and Fe are normally present in manganese ores, these could also potentially have CLOU properties.
