摘要
Most lead scrap recovered for recycling consists of car batteries, sheet and pipe from demolition of old buildings and sheathing stripped from old cables. There is also a quantity of leady dross recovered from refining operations. The equipment and procedures used in lead refining have not changed significantly in recent years. However, with the introduction of new stricter anti-pollution laws in many countries, lead refiners are reassessing their practices. 6 refs.
