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.

2016-8-31  Manganese. Mine development. Abstract: Development of the manganese ore deposits on Groote Eylandt prior to the Agreement dated 9th September, 1969, was carried out in two stages, namely: Stage 1 Development: Facilities were established to enable a production rate of 200,000 tons per annum of lump manganese of metallurgical grade to be achieved.

Mineralogy of the Groote Eylandt manganese oxides:

1988-11-1  Texture Pyrolusite differs from most of the Groote Eylandt manganese oxides in forming blocky euhedral crystals, up to a maximum (observed) size of 10ram. The mineral commonly occurs as polycrystalline aggregates showing sections of the ditetragonal prism and pyramid, with the (110) cleavage of the former common.
