The Operational Model

The OPERATIONAL MODEL is a process engineering compendium that has been developed by Alexis Yovanovic since 1987 for several mineral processing mechanical operations. It establishes an analogy with chemical processes creating a new phenomenological interpretation for both the Comminution and the Concentration with Mineral Particles Transfer. The Operational Model defines how mineral particles would behave if they were molecules, always guiding them along the shortest path, just like the GPS for a driver.
