Copper extraction - Wikipedia

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

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).
