manganese fact sheet - Proactive Investors

Manganese is mined as an oxide ore, converted to ferromanganese or silico-manganese in a blast or electric arc furnace, and then mainly used as an essential ingredient in the steel production process. Manganese Ores are processed in a variety of ways, eventually being used to alloy steels. They add a host of properties.
