SORTING MINED MATERIAL

摘要

A method of sorting fragments of mined material is disclosed. The method comprises exposing the fragments to a source of heating to heat the fragments depending on the susceptibility of the material in the different fragments to the source of heating. The heated fragments are thermally analysed using the temperature of each of the fragments as a basis for the analysis and are sorted into two or more streams on a fragment by fragment basis of the temperature of each fragment relative to a set point temperature. The method further comprises monitoring the grade of the ore in one of the ore streams on a bulk basis and changing the set point temperature based on the monitored grade of the ore in the ore stream. Also disclosed is an apparatus for sorting fragments of mined material.
