It is important to recycle cans because they are made from valuable materials. Write a paragraph to describe how steel and aluminium cans can be separated using a magnet
Answers
Answer:
Magnets are a vital tool used in recycling. Recycling consists of separating different types of metals and alloys, based on the elements each is made from. Many metals contain iron, and a magnet sticks to these types. Other metals do not contain iron, and therefore a magnet will not stick to them. Using a magnet determines if metals contain iron or not, and this plays an important role in recycling.
Ferrous Metals
Ferrous metals are any metals that contain iron. This includes tin, steel, iron, cast iron and plate and structural steel. A magnet is used to detect if a metal contains steel. If it does, the magnet sticks to the metal. The value of steel, or iron, products is significantly less than that of nonferrous materials.
Crane Magnets
Recycling centers or scrap yards often use a crane with a huge magnet. The crane operator moves scrap metals into piles using this magnet. Any ferrous material, or material containing iron, is picked up by the magnet and placed in a specified location. Any material that is not picked up by the crane’s magnet gets sorted by the type of metal it is.
