2022-1-27  The resulting copper matte consisting of Cu 2 S is then roasted to change all sulfides into oxides. 2 Cu 2 S + 3 O 2 ---> 2 Cu 2 O + 2 SO 2. The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O ---> 4 Cu + O 2. This step exploits the relatively easy reduction of copper oxides to copper metal.
