Smelting involves heating the crushed ore in a furnace to a very high temperature – over 1000 degrees C. Heating of the ore to such a high temperature removes the sulphur component of the lead sulphide (galena), either transforming the lead sulphide to lead oxide or to the metal itself. Pure lead itself melts at a relatively low 327 degrees C ...
