The term "Lead scrap" here refers to metallic lead and lead-containing materials that have lost their original functionality due to aging, breakage, damage, or end-of-life, or although not completely losing their utility, have been discarded during the production and use processes in industries such as metallurgy, batteries, chemicals, machinery, and building materials. After collection, classification, crushing, smelting, and other processing, this type of waste lead can be recycled as a lead resource and reused in applications such as recycled lead ingots, lead alloys, battery manufacturing, and chemical raw materials.
