mineral processing technology and mineral processing equipment

In mineral processing plan t , By creating an environment comprimising a magnetic force (Fm), a gravitional force (Fg) and a drag force (Fd) magnetic particles can be separated from nonmagnetic particles by Magnetic Separation. Competing forces • Gravitational force (Fg) determined by particle size and particle density. • Hydraulic force (Fd) for wet magnetic separators, determined by particle diameter, shape, liquid viscosity and velocity (see wet LIMS and wet HGMS below.) • Centrifugal force (Fc) for rotating dry magnetic separators, determined by particle size, density and drum speed. (see dry LIMS below.) • Air drag force (Fa) for dry magnetic separators, determined by particle size, density and air velocity. (see dry HGMS below). Separator Types Wet LIMS = Low Intensity Magnetic Separator • Wet separation of ferromagnetic particles • Magnetic field in separation zone * = 1-3 kGauss * approx. 50 mm (2 inches) from drum surface Wet HGMS = High Gra...
