An Introduction to the Chemistry of Metal Extraction

Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide. Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.

Microscale extraction of copper | Experiment | RSC Education

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.
