Abstract
Recent improvements in idustrial technologies require more critical purification of raw materials to obtain the optimum charachteristics of final products.
It has brought up new technologies of material purification, which includes newly developed rare earth permanent magnetic materials and improved magnetic separation technologies. The paper will discuss possibilities of applying rear eath magnetic separation to those area where permanent magnetic separation has been considered impractical or impossible. The paper will also introduce most recent applications of purifying industrial minerals or maetalic minnerals using those newly developped magnetic separation method.
