    Extracting Lead Materials from Ore

    First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt. Next the lead powder is put through a process, that involves mixing the lead ore , the addition of pine oil and the introduction of air bubbles and agitation which forms an oil froth, containing the lead ore, on the surface.
