extracting metals from their ores

  • Extraction of Metals Good Science

    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.
