Detailed Solution. Download Solution PDF. In the extraction of copper from its sulphide ore, copper is obtained finally by oxidation of cuprous sulphide with Cu2O C u 2 O. Cu2S + 3 2O2 → Cu2O+SO2 ↑ C u 2 S + 3 2 O 2 → C u 2 O + S O 2 ↑. Cu2S +2Cu2O→ 6Cu(I)+SO2 ↑ C u 2 S + 2 C u 2 O → 6 C u ( I) + S O 2 ↑.
