Ores and Minerals - Introduction, Extraction ...

As these metals have more affinity towards oxygen than carbon so ores of these metals cannot be reduced to their oxides as extraction of these metals from their oxides will be more difficult and expensive. These metals are obtained from their ores by electrolytic reduction. For example, sodium metal is obtained by the electrolysis of its molten chloride. In this process metals are deposited at ...
