Production of Recycled Lead. Lead has the highest rate of recycling of all metals. Because of its corrosion resistance, lead scrap is available for recycling decades or even centuries after it is produced. New environmental regulation in many countries has greatly reduced the dissipative uses for lead such as paint, leaded gasoline, pigments, stabilizers, solder, and ammunition. At present time, just under half of the total world lead production of 7.62 million tons comes from recycling of scrap materials.
