MAGNETS FOR THE RECYCLING AND MINING SECTOR
In recycling chains, there is a need for high magnetic power, the magnets of choice are neodymium magnets, thanks to their great strength over their competitors. At IMA we can manufacture the most suitable neodymium magnet for each application, meeting the requirements demanded by our customers in the best way.
Magnets play an important role in the recycling and mining sector.
In recycling, magnets are used to separate non-ferrous metal materials from other materials in a sorting process. Similarly, magnets are used in the separation of recyclable materials, such as aluminum cans, plastics, and paper. These materials are often mixed with ferrous materials such as nails, screws, and iron fragments. Magnets can be used to separate these ferrous materials from non-ferrous materials, which makes the recycling process more efficient and cost-effective.
In mining, magnets are used to separate ferrous minerals such as iron and steel from non-ferrous minerals such as copper and gold. Neodymium magnets are one of the most popular choices in recycling due to their strong attraction power. These magnets are very small and lightweight, making them easy to handle and transport. In addition, neodymium magnets are resistant to corrosion and oxidation, making them durable and suitable for a harsh working environment.
This separation is essential to ensure that valuable minerals are recovered efficiently and that contamination of unwanted materials is avoided. Magnets are also used in the mining industry to remove iron and steel particles that can damage expensive machinery and equipment.
In the mining sector, the ore is obtained and mixed with other metal products. This can cause damage to the machinery used to extract the ore. For this reason, strong magnets are inserted at specific points in the machinery to prevent damage when transporting the substance and to ensure correct extraction of the material, separating it from the metal products.
Also, in the milling stages of the material, we must protect the equipment with magnets to reduce the risks in the process. To obtain finer minerals that are sensitive to product contamination, such as salt or quartz, the mineral must be freed of metallic substances to provide maximum purity of this material.
The mineral powder obtained in the extraction process must be processed and separated from all metallic particles, to ensure the correct maintenance of the equipment and a high level of purity. Magnetic systems such as drums, filters, or separators are responsible for separating and filtering these minerals.
In recent years, the demand for this type of magnet for the separation of metallic particles has increased due to the scarcity of certain raw materials and the increase in the cost of waste disposal. This has led to an increase in recycling.
The recycling sector also needs to separate the material to be used from the metallic elements. The greater the amount of carbon in these products, the more magnetic properties they have and the easier they are to separate. Some of the most commonly used magnets in this sector are electromagnets, with the advantage of activating and deactivating their magnetic field. They can be found in the first waste sorting.
