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.

Our Services

In hard times we are responsibly creative.


A service for the Operational Control and Process Engineering support that uses information available at the plant to bring control to the plant floor and safety to the Managerial and Corporate Environments. This system is the last stage of a consulting project and becomes a customized software, exactly tailored to the needs of the operation.
