    Reagents in iron ores flotation ScienceDirect. Feb 01, 2005 3 Cationic collectors Primary fatty amines, utilised in the pioneer U process, are no longer employed in the flotation of iron ores They were modified with the insertion of the polar group (O–CH 2) 3 between the radical R and the polar head NH 2 of the primary amine Due to the presence of the covalent bond C–O, characteristic of

  • Beneficiation of Iron Ore Mineral Processing &

    24/05/2016· silica flotation reagents A cationic reagent is usually all that is necessary to effectively activate and float the silica from the iron. Since no prior reagents have come in contact with the thoroughly washed and relatively slime free magnetic iron concentrates, the cationic reagent is fast acting and in some cases no prior conditioning ahead of the flotation cells is necessary.
