The extraction of metals CPD RSC Education
2019-12-11 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. • Oxidation occurs when a metal (or carbon) gains oxygen, to form an oxide compound. Ideas for the classroom

Reduction of Metals (Extraction from Ore) - A-Level
Reduction of metal halides with metals. In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium.

2018-9-24 It is easier to obtain a metal from its oxide as compared to its sulphide and carbonate because when we extract metal from its respective ore, we have to perform calcination or roasting step in which carbonates and sulphides of metals are converted into metal oxides. hence in the case of oxides, we can skip this step and directly reduced oxides to obtain the metal.
