Introduction to Magnetic Separation: A Key Industrial Process
The magnetic field is used compellingly in many industries today, effectively aiding with the separation of materials, as well as with the separation of magnetic and non-magnetic components. With this method, magnetic separators yield a specific level of the magnetic field which is able to hold and attract the appropriate frequency of the materials that are magnetic while non-magnetic materials pass freely. Sectors such as mining, food processing, recycling, and water treatment implore its help. The efficiency of magnetic separation grapples just as much importance in the industries mentioned as does precision to maintain the quality and recovery of the product.
The differences in the values of the constituents magnetic properties, opens up the possibility of separating them. The collective outcome of the quantity of the magnetic fields intensity and strength plays great importance on how well this process runs. A mixture can be recovered of some kind of magnetic materials such as, iron and certain minerals that do react to the field. Some of important instruments in this process are magnetic pulleys, overhead magnets, drums, and so forth.
