método e aparelho para classificar minerado e métdo para recuperar material valioso

摘要

A method of sorting mined material to separate the mined material is disclosed. The method comprises exposing particles of the mined material to microwave energy and heating the particles depending on the susceptibility of the material in the particles. The method also comprises thermally analyzing the particles using the temperatures of the particles as a basis for the analysis to indicate composition differences between particles and sorting the particles on the basis of the results of the thermal analysis. The method also comprises controlling the temperature of particles as the particles are moved between a station at which particles are exposed to microwave energy and a station at which particles are thermally analyzed.
