Disintegration on heating of a Brazilian manganese

Abstract This pioneering study characterized the chemical, physical and mineralogical aspects of the Urucum Standard manganese ore typology, and evaluated some of its metallurgical characteristics, such as the main mineral heat decompositions, and the particle disintegration at room temperature and under continuous heating. A one-ton sample of ore was received, homogenized and quartered.

Particle disintegration of an important Brazilian

The lump ore from Morro da Mina mine had low manganese content in comparison to the oxidized ores and an intermediary Mn/Fe ratio. These characteristics, associated with the high SiO2, Al2O3 and CaO contents, may be responsible for a low metal/slag ratio, which may produce a highly reactive basic slag.
