Digital twin with automatic disturbance detection for an expert-controlled SAG mill

Paulina Quintanilla, Francisco Fernández, Cristóbal Mancilla +2

This study presents the development and validation of a digital twin for a semi-autogenous grinding (SAG) mill controlled by an expert system. The digital twin integrates three key…

Experimental implementation of an economic model predictive control for froth flotation

Paulina Quintanilla, Daniel Navia, Stephen Neethling +1

We present the implementation of a novel economic model predictive control (E-MPC) strategy for froth flotation, the largest tonnage mineral separation process. A previously calibr…

Grey-box Recursive Parameter Identification of a Nonlinear Dynamic Model for Mineral Flotation

Rodrigo A. González, Paulina Quintanilla

This study presents a grey-box recursive identification technique to estimate key parameters in a mineral flotation process across two scenarios. The method is applied to a nonline…
