Copper is the most noble of the first row transition metals and occurs in small deposits in several coun- tries. 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)`. The extraction of copper from chalcopyrite involves partial roasting, revoval of iron and self -reduction.
In self -reduction, the reducing species is

A
