Extracting and Refining Metals from Ore. Metals exist in the earth's crust either as native metals (elements) or minerals (compounds).; The rocks and sand in which metal deposits are found are known as ores.; Metal ores are mined from the earth's crust, then metals are extracted from the ore.; The form in which a metal exists in an ore depends on its chemical reactivity.
