PROPERTIES OF MANGANESE ORES AND THEIR CHANGE

2010-11-12  Groote Eylandt (GE) ore is a high-grade ore with a manganese content of 55 wt% (71 wt% MnO). The only phase identified in GE ore by XRD was MnO2 (pyrolusite). However, optical analysis and SEM revealed the complex mineralogical structure of the ore. Apart from pyrolusite, GE ore contained iron silicate and silica; pyrolusite grains were distinguished by the colour given by different impurities.
