METSIM International

METSIM accurately simulates a wide variety of inorganic chemical, hydrometallurgical, and pyrometallurgical processes with over 200 unit operations. It supports both steady-state and dynamic simulation modes and operates through a modular architecture: Base Module (mass balance, flotation, leaching, SX/EW); Mine Module (import drill-hole data and block models); Comminution Module (crushing, screening, grinding, classification, dense media, coal preparation); Heat Balance Module (pyrometallurgy, thermodynamics); Dynamic Simulation and Heap Leaching Module (time-dependent modeling, PID controllers, heap leaching with chemical reactions and weather modeling); Equilibrium Module (OLI Systems electrolyte integration); Costing Module (OPCOST capital and operating costs); and Engineering Module (equipment sizing, process control simulation, operator training interfaces).
