    Extracting Metals by Electrolysis

    Methods of extracting metals There are two main methods of extracting metals from their ores: reduction with carbon electrolysis (using electricity). The method of extraction which is most appropriate depends on the reactivity of the metal being extracted. Most metals are found combined with other elements, as compounds in ores.

    Refining (metallurgy) - Wikipedia

    In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and ...

    Whatever method is used to manufacture copper from its ore, its final purification is by electrolysis (Figure 6). Slabs of impure copper (blister copper), together with thin sheets of pure copper metal or stainless steel or titanium are immersed in a solution of copper(ll) sulfate (0.3 mol dm -3 ) and sulfuric acid (2 mol dm -3 ).

    Distillation Method This method is useful for purification of those volatile metals which have low boiling points such as zinc and mercury. In this method, the impure metal is heated to its boiling point in a vessel. The vapours of metal thus formed are collected and cooled in a separate vessel to get pure metal. The impurities being non-volatile remain behind. 2. Liquation Method By this ...
