2 CuFeS2 + 6 O2 Cu2O + Fe2O3 + 4 SO2

This is an oxidation-reduction (redox) reaction:

2 CuII + 2 e- 2 CuI (reduction)

4 S-II - 24 e- 4 SIV (oxidation)

2 FeII - 2 e- 2 FeIII (oxidation)

12 O0 + 24 e- 12 O-II (reduction)

CuFeS2 is an oxidizing agent, CuFeS2 is a reducing agent, CuFeS2 is a reducing agent, O2 is an oxidizing agent.
