Supervisory control and decoupled MIMO PID regulation for a pilot-scale copper flotation column using PLC, OPC, and industrial HMI.

After reading "Gaussian process regression for modeling computational and experimental mineral processing data" by Eskanlou et al. (Mineral-X, Stanford), I applied their GPR workflow to my own Cu-Mo plant flotation data and inverted it for the window that minimises Cu in the Mo concentrate.
