Magnetic projection: A novel separation method and its first
Magnetic projection is totally different from traditional magnetic separation. Traditional magnetic separation can only separate objects according to the magnetic susceptibility (Goldman et al., 1974), such as the separation of ferromagnetic materials and non-ferromagnetic materials. It separates the diamagnetic substances based on …

Magnetic Separation
Magnetohydrostatic separation is a method used to sepa-rate nonmagnetic particles immersed in a magnetic fluid by adjusting the magnetic buoyant force on particles with a magnetic field gradient. Magnetic separators are classified in terms of the differ-ence of the separation mechanism (Table 5.16.2).
