2021.6.26 Magnetic Separation Principle. Magnetic separation is a beneficiation method that uses the magnetic difference between minerals in a non-uniform magnetic field to separate different minerals. Magnetic separation is the most commonly used beneficiation method for ferrous metal ore such as iron ore. It is divided into weak
