copper iron flotation

  • Mining

    ASD is used to depress copper and iron sulfides in the copper/moly flotation circuit. It is also used as a sulfidizing agent to treat oxide ores. ASD can be used by itself or in conjunction with NaHS.


    The effect of sulphite ions on the xanthate-induced flotation of copper-activated pyrite has been studied. Various techniques have been used to identify the plausible mechanisms of interaction of sulphite with both collector and pyrite surface. It was found that sulphite depressed the xanthate-induced flotation of copper-activated pyrite with nitrogen or air purging at pH 7.

  • A Review on Novel Techniques for Chalcopyrite Ore Processing

    The copper (II) ion in the chalcopyrite is reduced to copper (I) sulfide which is reduced further to copper metal in the final stages. The iron in the chalcopyrite ends up converted into an iron (II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns to sulfur dioxide gas.
