manganese magnetic and flotation
Manganese: Mining & Transport
Crushed and screened ore may be concentrated by washing, sink-float, jigging, tabling, flotation, dense media separation and high intensity magnetic separation to produce a saleable concentrate. Carbonate manganese ores may be calcined. Higher-quality fines may be agglomerated, nodulised, sintered or pelletised.
