Abstract: A method for operating an ore comminution circuit is provided. The method includes obtaining at least one sensor signal related to an ore feed to the comminution circuit; determining a first ore grindability parameter of the ore feed from the at least one sensor signal, using a model; determining a second ore grindability parameter using parameters of the comminution circuit and/or of at least one comminution device in the comminution circuit; and updating the model with the second ore grindability parameter and the at least one sensor signal.
