Manganese oxide ores and carbonate ores are two main natural minerals on earth for extraction of manganese. ... and the flotation behaviors of manganese ores and iron ores indicated that the slurry system was very complex due to the dissolution of Mn 2+, Mn 4+, Fe 2+ and Fe 3+ ions.
In this study, manganese carbonate (MnCO3) was precipitated by mixing an aqueous solution of manganese sulfate (MnSO4 containing 85% Mn2+) and sodium carbonate (Na2CO3) in different proportions.
This manganese processing method is applied mostly for manganese carbonate ores or in combination with other methods like flotation to remove impurities. 4. Flotation Method. Flotation involves the use of chemicals (collectors) to selectively bind to manganese particles and allow them to float to the surface.

Since Mg carbonate flotation is so sensitive to pH, it is possible to selectively float dolomite from monazite ((REE)PO 4) using sodium oleate at pH 4 or by using flotinor 1682 (organic phosphoric acid) at pH 4 or 7; however, depressants and activators are necessary for a more effective separation . Various investigations indicated that Mg ...
04 Manganese carbonate flotation method. Manganese carbonate ore has more associated gangue, complex composition, and finer particle size.

The equilibrium is shifted toward carbonate by heating, or dilution, so that in this way, the carbonate ion reaches a concentration where manganese carbonate is precipitated from the complex, resulting in a further shift of equilibrium and eventual complete precipitation of manganese carbonate without substantial removal of ammonia.
(1) Carbonate-Gangue Ores—The carbonate gangue, such as calcite, is floated first with fatty acid, using an alkaline pulp and a starch or yellow dextrine to inhibit the manganese oxide. The pulp is then acidified and the …
Carbonate manganese ores may be calcined. Higher-quality fines may be agglomerated, nodulised, sintered or pelletised. Lower-quality ores, fines and complex fine-grained ores may be flotated. ... The ore may then undergo dense media separation after which, silicon waste is removed typically through flotation separation, and clays and other ...
