PROPERTIES OF MANGANESE ORES AND THEIR CHANGE IN THE

properties of a manganese ore have a large influence on the technology and efficiency of the production of manganese alloys. The melting and reduction behaviour of ores are defined by their chemistry, mineralogy and physical properties, which change as the ore is heated in a reducing atmosphere in a ferroalloy furnace.

Manganese Minerals Education Coalition

On Earth, manganese is never found as a free metal, but it is found in a number of minerals. The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production. The U.S., Japan, and Western Europe are all nearly deficient in economically mineable manganese.
