### The Extraction of Copper

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 into sulfur dioxide gas This is used to make sulfuric acid via the Contact Process An overall equation for this series of steps is: $2CuFeS_2 + 2SiO_2 +4O_2 \rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 \label{1}$...
