copper extraction and purification chemguide

2015-7-26  In the copper(I) sulphide, the copper is +1 and the sulphur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulphur dioxide, the oxygen has an oxidation state of -2 and the sulphur +4. That means that both the copper and the oxygen have been reduced (decrease in oxidation state).
