3.3.4 Copper extraction :: GCSE notes
2015-6-17 Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore can also be reacted with sulfuric acid to produce copper ...

Microscale extraction of copper Experiment RSC
In this experiment, students heat copper(II) oxide in the presence of hydrogen gas to extract copper. The copper(II) oxide reacts with hydrogen and is reduced, producing copper and water. This can be used to show the relative positions of copper and hydrogen in the reactivity series, and can also be used for percentage yield-type calculations.
