Metal recycling industry
The metal recycling industry encompasses a wide range of metals. The more frequently recycled metals are scrap steel, iron (ISS), lead, aluminium, copper, stainless steel and zinc. There are two main categories of metals: ferrous and non-ferrous. Metals which contain iron in them are known as Ferrous where metals without iron are non-ferrous.
Common non-ferrous metals are copper, brass, aluminum, zinc, magnesium, tin, nickel, and lead.
Non-ferrous metals also include precious and exotic metals.
Precious metals are metals with a high market value in any form, such as gold, silver, and platinum group metals.
Exotic metals contain rare elements such as cobalt, mercury, titanium, tungsten, arsenic, beryllium, bismuth, cerium, cadmium, niobium, indium, gallium, germanium, lithium, selenium, tantalum, tellurium, vanadium, and zirconium. Some types of metals are radioactive. These may be “naturally-occurring” or may be formed as by-products of nuclear reactions. Metals that have been exposed to radioactive sources may also become radioactive in settings such as medical environments, research laboratories, or nuclear power
