Over geological time scales very few metals can resist natural weathering processes like oxidationThis is why only the less reactive metals such as gold and platinum are found as native metals.
Smelting usually requires a reduction agent or another chemical to separate metal from its oreIn the earliest smelters the reduction agent was carbon in the form of charcoalCharcoal burned with hematite ore for instance smelts ironElectrolysis separates metal from ore by using acid and electricityAluminum which burns at a very high temperature is extracted from bauxite by electrolysis.
