Verified by Toppr. The correct option is C +1,+3. Chakcopysite is an iron +copper ore.It' s formula is CuF eS2. It is a sulphide ore in it Cu is present in +1 oxidation state and iron is present in +3 oxidation state. It is a naturally occurring ore.
Chalcopyrite is 2 C u F e S 2 (C u 2 S + F e S + F e S 2 ), a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula C u F e S 2 . C u + 1 F e + 3 S 2 − 2 .
However 80% of the world copper production comes from the ore chalcopyrite (CuFeS2). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. 14. Partial roasting of chalcopyrite produces (A) CuS and Feo (B) Cu O and Feo (C) CuS and Fe2O3 (D) Cu O and Fe2O3.
Although there are several ores, 80% of the world copper production comes from the ore chalcopyrite (C u F e S 2). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. In the self-reduction step, the reducing species is:
