How is Scrap Metal Recycling Done

Summary: Taking scrap metal to a scrap metal recycler is always a good idea, as scrap metal recycling is beneficial to both the environment and the economy.

Fremont, CA: There is an evident demand for scrap metal recycling for a variety of reasons. One is environmental: permitting scrap metal to wind up in landfills creates a risk since such metals contain toxins such as mercury, which can contaminate neighbouring soil and ground water. The other aspect is cost: recycling scrap metal allows us to reuse those parts to create new metal goods, which is much less expensive than mining for ore to produce new metals. Recycling is also a great strategy to keep production costs down.

How is scrap metal recycled?

In the process of metal recycling, there are several steps. First and foremost, remember that ferrous and non-ferrous metals can both be recycled. Carbon steel, alloy steel, cast iron, and wrought iron are examples of ferrous metals, which are iron-carbon alloys. Whereas, aluminum, copper, and lead are some examples of non-ferrous metals.

The first is the procedure of collecting. There are many products that contain both ferrous and non-ferrous metals; for example, scrap vehicles are the most common source of ferrous scrap metal, but other sources include steel structures, ships, railroad tracks, farm equipment, and consumer scraps such as appliances, office furniture, and other items.

Sorting is the next phase, which entails separating metals from a mixed scrap metal stream or a trash stream including different materials. These materials are sorted using magnets and sensors in the automated recycling process.

The next step is processing, which involves shredding the metals. These shredded metals have a high surface-to-volume ratio and can be melted with less energy than mining ore for new metals would take. Scrap metal processing plants compress the metal in compactors so that it can be handled more readily on conveyor belts, and then shred the scrap into fine particles.

Then there's the melting. Scrap metal is melted in a big furnace, and each metal is then transported to a furnace specifically suited for that metal. The furnaces include fuel-efficient regenerative burners that reduce the amount of energy used, resulting in a low environmental effect.

The following step is purification, which is carried out to guarantee that the finished product is of high quality and devoid of impurities. Electrolysis is one of the highly used purifying processes.

The next and final stage is to solidify what has been purified. By allowing the melted metals to cool on the conveyor belt, they solidify. At this point, scrap metal is moulded into particular shapes that can be utilized to make a variety of metal goods.
