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…
