Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in ironore 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.

It is commonly obtained through manganese ore in the form of manganese oxide (also known as pyrolusite), or through iron ores. Manganese production is thus often subsumed under iron mining. Besides their ores being regularly obtained from the same mines, manganese and iron are further linked due to their complementarity in steel production.
