Magnetic separation depends on 3 factors: 1. Magnetic force → is reflected in the number of gausses. 2. Gravitational force → this force refers to the distance between the centers of gravity, of the particles. 3. Forces of attraction → this force is what we see when we bring the magnet closer to the mixture.
