Description
Summary:The new sorting system has been developed to achieve efficient separation at low mineral content levels. The system employs high sensitivity X-ray sensors providing multi-energy analysis, thus giving maximal information about processed materials. It makes it possible to analyse the internal structure of the particles and directly detect intrusions of minerals and metals like copper or gold. The paper describes sorting application examples for copper ore with metal content under 0.5% Cu. The sorting system still allows high efficiency analysis, quantification and removal of rock particles representing waste fraction with no metal or a negligible amount, being uneconomic to process. This brings a huge advantage, where almost no losses of valuable minerals in the waste fraction are achieved. The presented sorting system has been developed by Comex and X-MINE EU Project Consortium.
