SORTING MINED MATERIAL

摘要

A method of sorting mined material, such as mined ore, is disclosed. The method comprises exposing particles of mined material to radio frequency electromagnetic radiation and heating particles depending on the minerals present in the particles and then thermally analysing particles exposed to radio frequency electromagnetic radiation to detect temperature differences between particles which indicate differences in the minerals in the particles. The method also comprises sorting the particles on the basis of the results of the thermal analysis.
