Digitalisation of ore composition and its benefits
Mined ore quality varies due to natural differences in mineral concentrations, irregular ore boundaries, and mining processes. Grade control systems attempt to segregate ore and waste so ore is sent to the process plant and waste is discarded. Variation is almost always present within the material sent to the process plant (Figure 1).
