Dec 11, 2019 An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. A metal can either be reduced or oxidised in a reaction. Reduction occurs when a metal in a compound loses oxygen, to form the elemental metal.

Oct 26, 2012 The usual methods of the mineral extraction cannot be used because (1) It can not be isolated by the reduction of its oxides it is very strong reducing agent. (2) It can not be extracted from the ores by the electrolysis of their aqueous solutions, as the formed metals will immediately react with water giving their hydroxides instead.

Oct 19, 2020 Why iron is extracted by heating its ore with carbon but Aluminium is not? Carbon is a good reducing agent to extract metals (from their corresponding metal oxides) that are less reactive than carbon itself. On the other hand, aluminium is more reactive than carbon and therefore cannot be extracted from its ores with carbon.
