Ore sorting involves identifying and removing waste and below-grade ore to preconcentrate the process plant feed. It produces higher, more stable head feed grades that essentially 'preserve' the processing capacity for economic ore – ore that holds higher value than the cost of processing. Ore sorting can reduce variability and deliver ...
