Method of obtaining largely pure iron scrap from mixture of metal scrap for smelting of high-grade steel, involves sorting copper and copper-containing components by sorter as other material components

摘要

The scrap metal is crushed by a shredder, a scrap shears or a granulator. The bulky and bar material is mechanically or manually separated by using a separators. The copper and copper-containing components are sorted by sorter as other material components. The ferrous components are separated from the rest portion of the mixture of metal scrap by magnetic sorters.
