The October 2012 Issue of Control Magazine features a case study on how Barrick used Mimic to save time and money on the startup of the largest gold mine in the world in Process Simulation Pans Out For Gold.
The Barrick, Pueblo Viejo project had all the warning signs for great startup and operational risks from the beginning.

Yet, the project team had two visionary leaders, Paul Yaroshak, Process Control Manager, and Benoit Bissonette, Plant Manager, who understood the value that a dynamic simulator could provide for preparing their operators for the challenges of the project. In order to meet the challenges of their project, Barrick decided to invest in a dynamic simulation to be used with their DeltaV process automation system. The goals of the investment of the dynamic simulation were:
We were fortunate to earn the trust of Paul and Benoit and the project began. After evaluating several options, the Pueblo Viejo project team decided to use Mimic Simulation Software. The reasons for their decision (in their own words) were:
Working with our partner, Lakeside Process Controls in Toronto, we began building the virtual gold processing plant. The solution was a modular, flexible dynamic simulator that can be run as independent, parallel training sessions:
The business results realized were greater than any the project team imagined with a payback of over 100X over the virtual plant investment. These benefits were due to a significant reduction in system commissioning time and early identification of system issues. In addition, the dynamic simulator provided an effective tool to familiarize the startup and operations staff with system and process complexities well before the startup of the plant. In addition, there were several unanticipated benefits such as:
In addition, Barrick used the virtual plant for off-line development of Standard Operating Procedures and as a test bed to improve operator training material. Finally, the operations trainers have a working system to develop on and not by memory and documents alone.
We appreciate the great capabilities of the Barrick, Pueblo Viejo team. Paul Yaroshak and Benoit Bissonette are knowledgable, talented professionals and their contributions were a major factor in the success of this project. We also appreciate the support and project management of our fantastic partner, Lakeside Process Controls. Finally, Jim Montague of Control, provided an excellent summary of the project in his article Process Simulation Pans Out For Gold.
I look forward to your comments, questions, or suggestions.
Hope to hear from you soon.
