Magnetic separation - Wikipedia

Magnetic separation can also be used in electromagnetic cranes that separate magnetic material from scraps and unwanted substances. This explains its use for shipment equipments and waste management. Unwanted metals can be removed from goods with this technique. It keeps all materials pure. Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the rec…

What is Magnetic Separation? - Busch Systems

Aug 10, 2016· Magnetic Separation systems were first used after the Second World War in scrap yards. These magnetic systems were mostly electromagnets, bulky, expensive items that relied on a power source to work and were notorious for overheating. The development of ceramic materials made it possible for permanent magnets to be used for separation.
