Metals, Extracting metals, displacement reactions
Metals and their extraction. Most metals in the Earth's crust are found as oxide or carbonate compounds. Rocks that contain a high amount of a metal compound that makes it economical to extract are called metal ores. For example, Iron ore haematite (iron oxide) and Aluminium ore bauxite (aluminium oxide).

Extracting metals with charcoal Learn Chemistry
This extraction experiment consists of two competition reactions. A metal oxide is reacted with charcoal. If the charcoal (carbon) is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel. Start with an oxide of lead, then observe what happens to an oxide of copper.
