Steps Involved in Scrap Metal Recycling Process

Scrap metal can come in an almost infinite variety of shapes, forms, sizes, materials, and other characteristics when sold. Scrapyards and people trying to sell their scrap metal are where metals are collected.

FREMONT, CA: Nowadays, metal is used in almost everything. Metal is used extensively in automobiles, airplanes, trucks, trains, buildings, and infrastructure. Scrap metal recycling is becoming increasingly common as a means of preserving the environment, particularly as more people discover they have scrap metal they did not realize they could sell. But what does it really mean to sell scrap metal for recycling? What steps does scrap metal take to be recycled and repurposed in an environmentally friendly and efficient manner? Following are the steps of the scrap metal recycling process.

Collecting

Scrap metal can come in an almost infinite variety of shapes, forms, sizes, materials, and other characteristics when sold. Scrapyards and people trying to sell their scrap metal are where metals are collected. It is a fundamental first move but is also critical. This is what motivates people to sell scrap metal that can be recycled.

Sorting

Metals are separated into recyclable and non-recyclable groups after they are obtained. Since only high-quality metals can be used in the recycling process, a stringent quality control system is used to ensure the best results. If lower-quality metals are used, the finished product will not meet the appropriate specifications for use.

Processing and Shredding

The metals are compacted to the smallest possible size to ensure that the manufacturing step runs smoothly. This is so they can integrate on the conveyor belt appropriately. They are shredded after they have been compressed. Shredding the metal breaks it down into tiny fragments, making it easier to melt in the furnace. Due to higher surface area to volume ratios, melting the fragments uses less energy and time than melting the entire parts.

Melting

Scrap metal is melted into molten form in large furnaces. Each type of metal has its own furnace, which is heated to the correct temperature. Depending on the amount of metal being melted and the type, the melting process can take minutes or hours. Although this process consumes a significant amount of energy, it is still significantly less than the energy required to produce fresh, new metal from raw materials.

Purification

The metals must be purified after melting to ensure there are no flaws. This is done to ensure that the new metal is of the highest quality and ready to use since impurities can dramatically reduce the metal's properties. This can be done in a variety of ways, but one of the most common is electrolysis. This is the electrochemical reaction that occurs when a direct current is applied to it. The metals are purified and then placed in a cooling chamber where density-increasing chemicals help them take physical shape.
