What is Extraction of Metals?
Within Chemistry, which covers atoms, bonding, reactions, the periodic table, organic chemistry and the chemistry of everyday life, this topic explains Extraction of Metals. Chemistry links what you can see in the lab to the particles and bonds behind it, so each topic here shows that link in a model.
Check that you can explain Extraction of Metals in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Extraction of Metals helps you explain why substances behave as they do, from cleaning products and food to medicines.
Extraction of Metals in detail
Metals found as ores, compounds in rock, must be extracted. Metals less reactive than carbon, such as iron, zinc and copper, can be extracted by heating with carbon, which removes the oxygen in reduction. In the blast furnace, carbon monoxide reduces iron(III) oxide to iron.
Metals more reactive than carbon, such as aluminium, must be extracted by electrolysis of the molten compound, which needs a lot of energy. Unreactive metals such as gold occur native. Mining and extraction have environmental costs, so recycling saves energy and resources.
