Bioleaching Copper Process In Morbi

A method of leaching copper from copper sulphidecontaining concentrates such as chalcopyrite includes using pyrite as a catalyst for ferric reduction in order to eliminate passivation of the chalcopyrite surface the process being carried out under conditions whereby the pyrite is not materially oxidized for example by maintaining the operating solution potential at a suitable level
