After concentration of ores we must now extract metal from in it This step will give us metal in its pure form ie the native form of we must convert the ore to a suitable form The metals need to be in an oxide form for the reduction process to be easier Hence the ores are converted to oxides so it is ideal for reduction

Methods of extraction Many metals are found in the Earths crust as ores 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
