Flotation Manganese Ore Froth Flotation (Sulphide

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).
