RECYCLING OF LEAD

RECYCLING OF LEAD Lead is a material which is very easy to recycle. It can be re melted any number of times, and provided enough processes to remove impurities are performed, the final product RECYCLING OF LEAD Lead is a material which is very easy to recycle. It can be re melted any number of times, and provided enough processes to remove impurities are performed, the final product (termed secondary lead) is indistinguishable from primary lead produced from ore.
