    The least reactive, like gold and silver, occur 'native' which means that they exist as the metal itself. Extracting them is just a matter of chipping them out of the rocks. That does require some physical effort, but it does not involve the need for any chemical reactions. Metals a little higher than gold and silver occur as compounds, usually the oxide, and so they need to be chemically extracted (smelted).
