Streamlining the steps to optimized production: Pre-project process modeling; Simulator based training; and Advanced control for optimized operation – case studies
This paper describes the techniques used by two different mining projects to streamline the steps from pre-project to optimized production. Prior to construction the Newmont Conga project utilized a dynamic model of the process to help refine the P&IDs so that the process design was integrated with equipment and control design. Design deficiencies were flagged and corrected with the use of a dynamic process model.
The Antofagasta copper mine Minera Los Pelambres in Chile utilizes an advanced control loop system for optimized operation of the SAG mills, Ball mills, and the Flotation area. Difficulties of traditional PID control are overcome by utilizing a model predictive controller with mining specific capabilities.
Minera Los Pelambres also utilized the remote support capabilities of ANDRITZ to train process operators on difficult pipeline operations. Pipeline operators were trained to start up, shut down, react to various emergency scenarios, and operate the three pipelines using a replica of the pipeline control system connected to a dynamic pipeline model at the ANDRITZ remote support center in Santiago.
