Abstract
Disclosed is a system and method for sorting copper-bearing ore to select portions having a target copper content. The system includes an analysis and selection station including first magnetic resonance analyzer measuring the copper content of input ore and a controlled diverter to divert portions of the input ore to a collection path when the copper content meets or exceeds a predetermined cut-off value. The predetermined cut-off is adjusted by a controller in response to the first magnetic resonance analyzer. A second magnetic resonance analyzer measures the copper content of the ore in a product path. That measurement is fed back to the controller to fine tune the adjusted cut-off value above, up or down, to optimize the yield of ore having the targeted copper content. The system may include a station for sizing the input ore, a station for sizing the output ore, and a station for sizing waste produced by the system.
