Copper is the most noble of the first row transition elements it occurs in small deposits in several countries. Ores of Copper include chalcanthite `(CuSO_4.5H_2O)`, atacamite `[Cu_2Cl(OH)_3]`, cuprite `(Cu_2O)`, copper glance `(Cu_2S)`, and malachite `[Cu_2(OH)_2CO_3]`. However, `80%` of the world copper production comes from the ore chalcopyrite `(CuFeS_2)`. Extraction of copper from chalcopyrite includes roasting, iron removal, and self-reduction.
Q. Partial roasting of chalcopyrite produces
