copper extraction and purifi ion - chemguide
The copper II ions in the chalcopyrite are reduced to copper I sulphide which is reduced further to copper metal in the final stage . The iron in the chalcopyrite ends up converted into an iron II sili e slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas. This is used to make sulphuric acid via

Thus the ferrous iron is oxidized in ferric iron which precipitates in iron hydroxide Fe OH 3. The precipitate is then separated from water by filtration on sand or decantation. The stage of precipitation by chemical oxidation can also be carried out with the stronger oxidants such as the chlorine dioxide ClO 2 ozone O 3 or the potassium permanganate KMnO 4 .
