Beneficiation of manganese ores with particular reference

2018-6-7  manganese ores. Most manganese ores due to their complex mineral association and their variable physical characteristics present many beneficiation problems some of which cannot be overcome satisfactorily. The manganese deposits of Fiji are becoming increasingly important but before many of them can be exploited a cheap beneficiation process will be required.
