Beschreibung
Zusammenfassung:	A method of sorting mined material for subsequent processing to recover valuable material, such as valuable metals, from the mined material is disclosed. The method includes a combination of selective breakage of mined material (for example, by using microwaves and/ or high pressure grinding rolls), subsequent size separation, and then particle sorting of a coarse fraction of the separated material based on differential heating and thermal imaging. L'invention concerne un procédé de triage de matériau minier en vue d'un traitement ultérieur permettant de récupérer un matériau de valeur, notamment des métaux de valeur, à partir du matériau minier. Le procédé comprend, dans l'ordre, les opérations suivantes: concassage sélectif du matériau minier (en utilisant par exemple des micro-ondes et/ou des cylindres de broyage haute pression), calibrage et triage des particules d'une fraction grossière du matériau séparé sur la base du chauffage différentiel et de l'imagerie thermique.
