A circular economy for metals is desirable in a world of scarce resources, but unfortunately any industrial system is characterised by energy use, material losses and inefficiencies. Quantifying the true recyclability of metals, exergetic losses and environmental impacts of processing primary and secondary metal sources requires rigorous simulation. Therefore, robust metallurgical simulation models are required for reactors and systems. Thence, this paper couples a dynamic model for a lead reduction TSL furnaces with a flowsheet model of an integrated copper/lead smelter to evaluate system performance. The TSL model predicts the distributions of several minor and technology elements, based on thermodynamic modelling and mass transfer parameters. The dynamic TSL model was developed using SimuSageTM, while the smelter model was developed with HSC-SimTM. Linking a dynamic unit model with a flowsheet model enables scenario analyses for a large set of operating conditions to maximize resource efficiency dynamically.
