Flotation Manganese Ore - Froth Flotation (Sulphide ...

2021-11-4  Haven't seen any pyrolusite flotation done, however no doubt possible based on other 'oxide' flotation systems. Just need to identify the surface charge (IEP, ZPC) of the manganese mineral as a function of pH, look up the surface charge of the gangue minerals at the various pHs and then select your collector(s) (anionic vs. cationic).
