  • Copper pyrites is an ore of copper. (i) Describe the,

    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.

  • Copper is extracted from copper pyrites by - Tardigrade.in

    25%. Solution: The formula of copper pyrites is C u F e S 2. In auto reduction, the sulphide ores of the metals which are less electropositive like H g, P b and C u are heated in the air so as to convert a part of it to its oxides. These oxides then react with the remaining sulphide ore in the absence of air, to give the metal and sulphur dioxide.
