A Review on Novel Techniques for Chalcopyrite Ore

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. This is used to make sulfuric acid via the contact process (copper extraction and purification). Overall equations for these series of steps are
