Abstract
A model is proposed to simulate the operation of a dry rotary drum magnetic separator. The model uses a probability distribution of the trajectories followed by the particles ejected from the rotating drum of the magnetic separator. Empirical relationships are used to relate the particle trajectories following their ejection to the drum rotation speed and magnetic field.
Highlights
Magnetic separation is widely used in mineral processing to separate valuable minerals from gangue minerals using the magnetic properties of the minerals [1]
Few papers dealing with the modelling of wet magnetic separator are available in the literature [5,6,7,8] and less can be found on the modelling of dry magnetic rotary drum separators [9]
This paper proposes a mathematical model for a dry magnetic drum separator and shows the application of the model to simulate a magnetic separation circuit consisting of interconnected dry magnetic separators
Summary
Magnetic separation is widely used in mineral processing to separate valuable minerals from gangue minerals using the magnetic properties of the minerals [1]. By adjusting the value of z to gate positions it is possible to simulate the operation of a magnetic drum separator from the knowledge of the ore distribution within the size/magnetic susceptibility class, i.e. xi; j;F .
