    Copper pyrites are concentrated by froth flotation process. In this process slurry of finely divided ore is taken in a large tank. Pine oil or eucalyptus oil is used as the frothing agent. Ethyl xanthate is added which is used as a collector (it increases the binding force between ore particles and forth). A mixture of all these things is agitated by current of air and froth is formed
