Hybrid non-linear model predictive control of a run-of-mine ore ...

The economic evaluation of a grinding mill circuit is done by using the relationship be-tween the grinding mill circuit product particle size and the separation concentrate recovery and grade curve [8]. Economic plant-wide optimisation for a mineral processing plant is therefore limited to the operating range of the grinding mill circuit [9].

Design of the Otjikoto Gold Mill, Namibia | SpringerLink

Mine operations consist of surface mining and a milling facility. The gold mill uses a modern gravity recovery/carbon-in-pulp (CIP) process to extract and recover gold from run-of-mine (ROM) ore. Initial mill design was for a throughput of 2.5 million tonnes per annum (Mtpa) but was then expanded to 3.1 Mtpa after 9 months of operation.
