Publication number: 20150314332Abstract: 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.Type: ApplicationFiled: November 29, 2013Publication date: November 5, 2015Inventors: Georgios DIMITRAKIS, Samuel KINGMAN, Christopher DODDS, Juliano KATRIB, Andrew BATCHELOR, Aled JONES

Publication number: 20150292056Abstract: The present disclosure provides an apparatus for treatment of mined material. The apparatus comprises a source for generating electromagnetic radiation and a microwave inlet region for exposing fragments of the mined material to the electromagnetic radiation. Further, the apparatus comprises a reflective structure adjacent the microwave inlet region and providing, or surrounding, a passage for guiding the fragments of the mined material to the microwave inlet region. The reflective structure is arranged to attenuate penetration of the electromagnetic radiation from the microwave inlet region into the passage during throughput of the fragments of the mined material.Type: ApplicationFiled: October 30, 2013Publication date: October 15, 2015Inventors: Georgios Dimitrakis, Samuel Kingman, Christopher Dodds, Andrew Batchelor, Aled Jones
