education CBSE CHEMISTRY X Extraction of metals

Extracting metal low in activity series The metals low in the reactive series are very less reactive. The oxides of such metals can be reduced to metals by heating alone e.g. mercury is obtained from its ore, cinnabar (HgS), by the process of heating .Extraction of metal using Heat is called Pyrometallurgy.
