In iron ore, where quartz is the major impurity, reverse flotation is preferred for the concentration of iron values. Several cationic collectors such as dodecylamine chloride (DDA), cetyl trimethylammonium bromide (CTAB), ether or ester amines, and quaternary ammonium salts are used as the flotation collector of quartz.
