Copper Mining and Extraction Sulfide Ores

Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining.

Reduction of Copper Oxide (solutions, examples,

In this activity, copper oxide is reduced by hydrogen to copper. 2CuO + H 2 → 2Cu + H 2 O Procedure 1. Weigh the reduction tube empty. 2. Place about 3 g of copper(II) oxide along the base of the tube so that it is spread out on the middle of the tube. 3. Reweigh and note the mass of the tube plus copper(II) oxide. 4. Clamp the reduction tube at its open end.
