Overview: We will be presenting our latest developments in ore stockpile modelling and its potential applications in mine-to-mill optimisation. Researchers at the JKMRC are developing a dynamic model of coarse ore stockpiles and ore bins for tracking ore movement and its properties such as grade and particle size. The model considers the feeding of ore, such as from a conveyor, and the flow of material on the surface of the pile as material tries to maintain an angle of repose, including and segregation by size that cause the periphery of the pile to become coarser. The model allows for extraction of ore from several draw points and the rate of draw affects how material works its way through the pile towards the discharge feeders. An important potential application of the model is for tracking geometallurgical data from the mine through to the mill feed where it can be used to optimise the control and optimisation of the process plant.
