1.	Copper is the most moble of first row transition meals and occurs in small deposits in several countries ares of copper include chalcanthite (CuSO_(4)5H_(2)O), afecamie (CuCHOH)_(3)), cuprite(Cu_(2)O) Copper glance (Cu_(2)S) and rolachite (Cu_(2)(OH)_(2)CO_(3)). However, 80% of the world copper production comes from the ore chalcopyrite (CuFeS_(2)). The extraction of copper from chalopyrite in polves partial roasting, removal of Iron self-reduction. In sell reduction the reducing species is
Answer» S `O^(-2)` `S^(-2)` `SO_(2)` Solution :In SELF REDUCTION the reducing SPECIES is `S^(-2).Cu_(2)S+2Cu_(2)O to 6Cu+SO_(2)`
