On the basis of reactivity metals are grouped into three categories —
- (i)Metals of low reactivity
- (ii)Metals of medium reactivity
- (iii)Metals of high reactivity Therefore metals are extracted in pure form from their ores on the basis of their chemical properties. Metals of high reactivity are extracted from their ores by electrolysis of the molten ore. Metals of low reactivity are extracted from their sulphide ores, which are converted into their oxides. The oxides of these metals are reduced to metals by simple heating.
