Expert Guide: Magnetic Separation in Mineral Processing
Magnetic separators employ an external applied magnetic field to pull out magnetic materials such as iron ore and ferrous metals.These machines work on the principle of applying magnetic force to pull out fine particles from the feed material. Electrostatic separators, on the other hand, work based on the conductivity of the minerals, whereby electrical fields are …
