Manganese Mining and Processing: Everything you Need to Know

Later, during Ancient Egyptian and Roman eras, manganese compounds added color to glass. Chemical studies of manganese during the 16th through 19th centuries led to the realization that the addition of manganese to iron ore-based steel made it even harder. In today’s world, manganese is often used for cathodic shielding in the battery industry.
