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 the organic function ether, reagents belonging to this
