Oct 07, 2008 Lead chloride is much more soluble in hot water than silver chloride. Leach the mixed chlorides with boiling water, let it cool and pour it off the PbCl2 crystals, reheat the water and use it again for another extraction. Repeat several times, until the weight of lead chloride is 3/4 or so of what youd expect for 100% lead as the starting metal.
