Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet.
Magnetic separation is an industrial process that uses a magnetic field to separate magnetic materials from non-magnetic ones. Iron, for example is highly magnetic; magnetic separation is sometimes used to separate iron ore from surrounding silicate rock. Magnetic separation can also be used to separate ferrous materials, or materials that contain iron, from industrial waste streams before they can contaminate water supplies.

Magnetic separation is a popular and low-cost method of recovering metals. In addition to the drum method, many other types of separators exist. These include, but are not limited to, pulleys, discs, belts and rings. Magnetic separation is used primarily by mining industries but also by environmentalists on industrial wastes and even by those who study space materials. Magnetic separators can be used either "wet" or "dry" and come in countless shapes and sizes.
