Abstract
A method of sorting fragments of mined material that includes valuable and non-valuable materials is disclosed. The method comprising heating the fragments by heating selected materials within the fragments and thermally analysing fragments of the mined material to determine the temperature of each fragment. The method further comprises sorting fragments on the basis of the thermal analysis to separate fragments having a temperature within a temperature band defined by a range between an upper temperature limit and a lower temperature limit from fragments having a temperature outside the temperature band. The upper and lower temperature limits are selected to identify fragments as containing an amount of valuable material that is economically viable to extract based on the fragment temperature. Also disclosed are an apparatus for sorting mined material and a method of recovering valuable material by sorting in according with the sorting method.
