Processing of Groote Eylandt Manganese Ores - AusIMM

The Groote Eylandt manganese ore deposits contain mainly pyrolusite and cryptomelane with lesser amounts of the manganese minerals lithiophorite, todorokite, psilomelane, and nsutite. The major non-manganese minerals which occur are quartz, kaolinite, and goethite. Determination of the mineralogy relies mainly on x-ray diffraction analysis.
