    Types Of Extraction Scool The Revision Website

    An ore is usually a compound of the metal mixed with impurities when the metal is dug up a method must be used to separate the metal from the rest of the ore this is called extracting the metal the method of extraction depends on how reactive the metal is the more reactive the metal the more difficult it is to extract from its compound

  • Gcse Chemistry Extraction Of Metals What Is Ametal

    Gcse Chemistry Extraction Of Metals What Is Ametal

    A metal below carbon in the reactivity series zinc to silver may be extracted by heating the metal ore with carbon during the reaction the metal in the ore is displaced from its nonmetal anion because carbon is more reactive than the metal carbon is used because it is cheap and readily available coke and charcoal are both carbon this form of extraction is less expensive than electrolysis the metal in
