==Key Stage 3==
===Meaning===
'''Extraction of Metals''' is how we get usable [[metal]] from [[ore]] found in the ground.
===About Extraction of Metals===
There are 3 main processes for the '''extraction of metals''':
*None - [[Element]]s below [[Hydrogen]] are found [[Native]] which means the [[metal]] [[element]] can be found not as part of a [[compound]].
*[[Smelting]] - [[Element]]s above [[Hydrogen]] but below [[Carbon]] are found in [[metal]] [[compound]]s so they need to be [[Extraction of Metals|extracted]] by using [[Carbon]] to [[Displacement Reaction|displace]] the [[metal]] from the [[compound]].
*[[Electrolysis]] - [[Element]]s above [[Carbon]] are found in [[metal]] [[compound]]s but they cannot be [[Extraction of Metals|extracted]] with [[Carbon]] because [[Carbon]] is less [[Reactivity|reactive]] than those [[metal]]s so we use [[electrolysis]] to [[Extraction of Metals|extract]] them.
