The use of frothers during the reverse cationic flotation of iron ores is not a common practice because the partially neutralised ether mono- and diamines used as collectors also act as frothers. However, several alcohol-based frothers were used during the reverse cationic flotation of iron ores in the USA and in Canada (Houot, 1983).

Why is the froth flotation method only used for sulphide ores?

Answer (1 of 6): This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil.
