Overview
A metal is a material of various opaque, fusible, ductile, and typically lustrous properties that are good conductors of electricity and heat, form cations by loss of electrons, and yield basic oxides and hydroxides[1].
Metal waste should be dealt with by recycling. Recycling of metals can include the following processes:
- Collection, weighing, sorting and distribution of metals: dealing with a wide range of suppliers, including engineering industries; small traders, such as plumbers or vehicle dismantlers; local authority collection sites; and householders disposing of domestic appliances.
- Shearing – reducing the size of large pieces of metal by cutting
- Baling/compacting – to improve ease of handling and transportation
- Shredding – reducing feedstock to fist-sized lumps; and separating metals from other materials using magnets and air classification methods. A large shredder can process a car in less than ten seconds.
- Media separation – further separation of any remaining non ferrous metals using liquid density and hand or mechanical sorting methods
- International metals trading – moving metals around the world[2].
