Lead scrap includes lead-acid batteries, cable coverings, pipes, sheets and lead coated, or terne bearing, metals. Solder, product waste and dross may also be recovered for its small lead content. Most secondary lead is used in batteries. To recover lead from a battery, the battery is broken and the components are classified.
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.

Electronic scrap components, such as CPUs, contain potentially harmful materials such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to the health of workers and their communities.
Mining, mineral processing and smelting activities in the area have produced gold, silver, lead and zinc for more than 130 years. Wastes generated during the mining and ore processing activities contained metals such as arsenic and lead at levels posing a threat to human health and the environment.
The formal geological name for the Lead Belt is the "Southeastern Missouri Mississippi Valley-type Mineral District". It contains the highest concentration of galena (lead(II) sulfide) in the world [2] as well as significant economic quantities of zinc, copper and silver and currently mined sub-economic quantities of metals such as cadmium, nickel and cobalt.

Scrap vehicles at Barry Docks. The process of recycling a vehicle is extremely complicated, as there are many parts to be recycled and many hazardous materials to remove. Briefly, the process begins with incoming vehicles being inventoried for parts. The wheels, tires, battery, and catalytic converter are removed. Fluids, such as engine coolant ...
It forms on the surface of low-melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal. For higher melting point metals and alloys such as steel and silver, oxidized impurities melt and float making them easy to pour off. With wrought iron, hammering and later rolling remove some dross.
