extraction of crude metal from concentrated ore

Expert Answer:

For a lot of metals (lead, mercury are good examples), the metal forms a weaker ionic interaction with a "hard" ion like oxide compared to a "softer" ion like sulfide. This weakens the ionic bonding in the solid and makes the metal ion more reactive.
Hence we convert the sulphides to oxides so that the extraction of the metals becomes easy .
