The exploitation of manganese-rich ‘ore’ to smelt iron in ...

Bloomery iron smelting in western Uganda produced manganese-rich slag. • Analysis suggests the use of a manganese-rich flux in addition to an iron ore. • Ethnographic data from the area reports the smelting of two combined ores. • Adding a Mn-rich flux may have positively impacted on the smelts. • Phosphorous levels were also noteworthy.

Manganese - USGS

Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore 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.
