Extraction processes The Reactivity Series potassium sodium calcium magnesium aluminium zinc iron copper gold (carbon) Increasing reactivity Metals above carbon must be extracted using electrolysis. Metals below carbon can be extracted from the ore by reduction using carbon, coke, or charcoal. Gold and silver often do not need to be extracted. They occur native. The reactivity of a metal determines the method of extraction. lead silver
