What’s involved in metal recycling?

Metal recycling has a long history. As early as WWII there were efforts to collectively save and reprocess metals to aid the war effort. Part of the reason for this interest is the ease of magnetically sorting steel and iron (ferrous metals). Modern recycling equipment can identify many kinds of metals, although more complex technology is required to separate non-ferrous metals.

Basic metal sorting involves separating ferrous from non-ferrous metals. Ferrous metals contain iron, and are attracted by magnets. This allows iron and steel to be pulled from a waste stream easily. Large pieces of scrap can be moved by cranes fitted with an electromagnet. This type of machinery is most often seen at automotive salvage yards.

Mixed or partially sorted waste streams contain easily identified fractions of ferrous metals and aluminum. When an electric current is induced across the materials, metals are affected, and any non-metal contaminants are not. This is known as eddy current separation. Most materials recovery facilities now use this type of metal recycling equipment. Even though aluminum is not magnetic, eddy currents can levitate it, allowing plastics to drop out of the process, and the aluminum to be removed.

Because of the value of copper, lead, gold, silver, platinum and palladium, if enough scrap can be collected, it becomes economically viable to recover precious metals from electronic waste. This process requires more technologically advanced metal recycling equipment. The use of sensors to identify metals through x-ray and infra-red scanning is becoming more common in large facilities.

Large-scale metal recycling of mixed materials is accomplished best by pre-shredding the items to reduce the size of the pieces. This increases surface area, and helps isolate smaller fractions.
