Ore Concentration The lead-rich ore, with a typical concentration range of 3-8% lead, must first be separated from other material (the gangue). The principle of using flowing water to wash away the lighter gangue particles, leaving the denser ore behind, has also been used since ancient times (e.g. Laurium, Greece, 5th century BC.
