  • Extracting Lead Materials from Ore

    Extracting the lead materials from the ore is a multi step process. 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 flotation process, that involves mixing the lead ore with water, the addition of pine oil and the introduction of air bubbles and agitation which forms an oil froth
