reagents for iron ore flotation process
Reagents in iron ores flotation - ScienceDirect
Feb 01, 2005 3. Cationic collectors. Primary fatty amines, utilised in the pioneer USBM 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 ...
