Ores and the reactivity clue

Reactivity series with carbon marked as the divider between electrolysis above and carbon reduction below, with silver and gold shown as sometimes uncombined

Most metals are extracted from ores because they are found chemically combined as oxides, sulfides or carbonates. An ore is a rock that contains enough metal or metal compound for extraction to be worthwhile.
