The first step in sorting metals is identifying whether they are ferrous or non-ferrous. Ferrous metals, like steel and iron, are magnetic, heavy, and may rust when exposed to moisture. In contrast, non-ferrous metals, such as aluminum, copper, brass, and stainless steel, are non-magnetic, more valuable, and resistant to rust. Using a magnet to perform this simple test allows you to quickly separate metals into these two main categories for further sorting.
After identifying ferrous and non-ferrous metals, sort them into separate containers to maintain their recycling value. Sorting by type reduces contamination and keeps the materials suitable for recycling. Labeling containers by metal type makes sorting easier and keeps your workspace tidy.
A visual inspection can further confirm the metal type and identify any mixed materials. Look for distinguishing features such as color, weight, and any markings. For instance, aluminum is silvery and lightweight, copper has a reddish hue, and brass appears yellowish. Additionally, some metals may have stamps or labels indicating their type, like "AL" for aluminum or "CU" for copper.
Prioritize high-value metals like copper and brass during sorting to maximize returns. For example, stripping insulation from copper wires can significantly increase their value. Similarly, separating brass from other components, such as screws or plastic parts, ensures you get the most value from your scrap. Sorting these metals first helps you get the most value from your efforts.

Recycling metal involves several key steps that transform discarded items into reusable materials, conserving resources and reducing energy use. This process not only reduces waste but also helps minimize the environmental impact of manufacturing new metals from raw ore.
At recycling facilities, the first task is to sort metals by type using advanced technologies like eddy current separators and infrared sensors, ensuring efficient processing. Proper sorting is crucial, as different metals require unique methods for recycling.
Next, large metal items are shredded into smaller pieces, increasing surface area for efficient melting. For instance, aluminum cans are reduced to small chips, while steel is broken down into manageable fragments. This step prepares the metal for the intense heat of the melting process.
The shredded metal is melted in a furnace, with each type requiring a specific temperature—steel needs about 1700°C, whereas aluminum melts at around 660°C. This precise control ensures that the metal transitions smoothly into a liquid state.
Once melted, the metal undergoes purification to remove impurities and meet quality standards. Techniques like electrolysis, chemical additives, or vacuum degassing are employed to refine the molten metal. These methods ensure the recycled material is as good as—or even better than—newly mined metal.
Once purified, the molten metal is poured into molds to form ingots, bars, or slabs. These molds are then cooled, often using water or air, to solidify the metal. The resulting shapes make it easier to transport and prepare the material for future use.
In the final step, solidified metal is transformed into new products through processes like rolling, stamping, or extruding. This allows the recycled metal to take on new forms, ready for use in industries like packaging, construction, and automotive manufacturing. For example, aluminum sheets can become beverage cans, while steel slabs might be used to build skyscrapers.
By properly preparing metal at home—cleaning, sorting, and removing contaminants—you help streamline recycling, improve efficiency, and produce high-quality recycled products. Small efforts in preparation have a big impact, making metal recycling a win for both the environment and the economy.
Recycling metal at home is an easy and effective way to manage small amounts of scrap metal.
