198 HEAVY MINERALS 2007 Dry magnetic separators, including both drum and roll types, generally offer far more precise separations than wet magnetic separators. Dry magnetic separation is more controllable since the separation medium is air rather than water. Separating particles from one another is naturally easier without having to fight drag forces created by water. This creates a distinct

Recent advances in magnetic separator designs and applications

Magnetic separation equipment for minerals processing generally falls into three basic categories: low, medium and high intensity, based on the relative magnetic field strength employed to accomplish separation. Low intensity magnetic separators (LIMS), are generally wet separators and are commonly used for concentration of magnetite, or for scalping of ferromagnetic materials. The LIMS

Magnetite Oresome Resources

Magnetite is the most magnetic mineral, and has been used as a lodestone or natural magnet in compasses in the past. As it is dense with a specific gravity of over five, it is used as a dense medium when mixed in mineral separation particularly in coal preparation. Importantly, magnetite is suitable for processing into iron ore pellets for use in modern steel production
