One of the most common applications of froth flotation is in copper mining. Copper ores often contain a mix of valuable copper minerals and waste material. Froth flotation allows miners to separate the copper minerals efficiently, resulting in high recovery rates. 2. Gold Extraction. Froth flotation is also used in the extraction of gold.

Excess frothers give misleading results, in that too much froth is produced, gangue minerals may be floated, selectivity is poor, and recovery is misleading. In non-sulphide flotation, frothers used may be the same as for sulphides, or sodium oleate, Emulsol X-1, Ninol, or an alcohol derivative may be used.
