Practical aspects of using beta-delayed gamma emission for copper ore analysis on a running belt conveyor

In this study, we investigated the feasibility of copper ore analysis on a running belt conveyor by measuring the delayed positron annihilation quanta based on the beta-decay of 62Cu, which was previously activated by a D-T, 14 MeV neutron generator. We constructed a model of a belt conveyor that measured 10 m in length to test this method. Our measurements demonstrated the feasibility of the method but practical constraints imposed by user demands and the industrial environment would make the design impractical and cost inefficient. •Mining company requested a lightweight, portable belt conveyor copper ore analyzer.•Technique based on delayed gamma neutron activation analysis was investigated.•Tests showed that the final device would be unwieldy and cost inefficient.
