Claim 11:
12. A method for mineral recovery in a mining operation, the method comprising a thickener including a process water input, an underflow output having an underflow controller for adjusting outflow of thickened slurry from the thickener, an overflow output for dispensing clarified water from the thickener, a flocculant input and a flocculant dilution input, wherein the method comprises:
employing a thickener controller to control an operation of the thickener; and
executing a mining operations generated model to issue commands to the thickener controller, wherein the mining operations generated model incorporates a thickener sub-model and a material sub-model, wherein the mining operations generated model is employed to predict a future state of a thickener based on inputs of sensed conditions in the thickener and predictions made by the thickener sub-model and the material sub-model in real time,
issuing in real time a command for change in at least one control parameter of the thickener controller, based on the predicted future state of the thickener, and
wherein the thickener sub-model utilizes a machine learning model, and a physical simulation of the thickener using a partial differential equation model, wherein outputs of the thickener sub-model are quantitative predictions of performance variables,
wherein the thickener sub-model is a prognostic model of the thickener and defines internal dynamics of the thickener to predict the future state from recent sensed conditions, future control settings, and predicted inputs from the material sub-model.
