Metals and NonMetals Occurance and Extraction of Metals

Extraction of Metals of high reactivity. Metals of high reactivity; such as sodium, calcium, magnesium, aluminium, etc. are extracted from their ores by electrolytic reduction. These metals cannot be reduced using carbon because carbon is less reactive than them. Electrolytic Reduction Electric current is passed through the molten state of metal ores. Metal; being positively charged; is deposited over the cathode.
