Process Simulation and Optimization Using Metsim

With more stringent environmental and economic constraints being placed on mining operations, it has become necessary to optimize each process to minimize energy and raw material consumption and reduce waste discharge. In most cases, detailed process analysis is required to detect inefficiencies and provide alternative solutions for process improvement. HETSIM, a microcomputer process modeling and simulation system, is routinely used to analyze communition, hydrometallurgical, pyrometallurgical, and coal preparation processes. The process modeling techniques used in METSIM, including process control simulation, will be presented and illustrated using actual plant processes.
