Burden Mix Optimisation for Metallurgical Recycling Processes

Abstract

The paper presents a hybrid approach for a techno-economic optimisation of the material input mix for a metallurgical recycling process. The approach combines chemical-physical process simulation with economic optimisation models and allows to model chemical-physical coherences adequately while maintaining linearity in the input-output relations of the optimisation model. The paper describes the problem and its background, the general approach, the main development steps, presents results of the optimisation and provides an outlook on further planning tasks as well as further processes on which the approach can be disseminated.
